Trek Checkpoint ALR 5 review – a confident, capable gravel bike

Trek's updated aluminum checkpoint is a surefooted, confidence-inspiring ride that's perfect for ruined back lanes, byways and well-laden travels.

BikePerfect Verdict

The reshaped Checkpoint frame neatly combines confidence-inspiring stability with a fun, engaging feel which goes well at all speeds on all sorts of surfaces. This might not be the lightest or fanciest build, but the key bits are great and the rest just quietly works.

Stable and predictable

Comfortable

Great shifting and brakes

Gearing a bit tall for the weight

Could use a dropper post

The aluminium-framed ALR models sit at the bottom of Trek's Checkpoint range, with the lighter carbon SL and race-focused SLR bikes above, but in truth that's not a bad place to be. The ALR 5 gets a full set of excellent Shimano GRX components for the drivetrain and brakes, decent tires on tubeless-ready rims and lots of rack and fender mounts. 

The result is a surefooted, confident bike that's ready for exactly what Trek says it's for – gravel riding for fun, commuting or just general adventures. Which is pretty much what most people are after when looking for the best gravel bikes or best cheap gravel bikes .

Design and geometry

For 2023, the Checkpoint frame has seen some changes – basically it's got longer both in the front centre and the chainstays, and the stem is shorter to compensate. I tested a 58cm, and compared to the 2021 model it has 10mm longer chainstays, 20mm more reach and is 26mm longer overall. The 90mm stem and 60.9cm/41.1cm stack and reach figures keep the overall riding position fairly relaxed, with a usefully tall front end and slightly head-down, but certainly not front heavy, bias.

The head angle is the same as before at 72.3 degrees, presumably to keep the steering decently snappy, as is the bottom bracket drop at 7.4cm. 

This might be the 'poor man's' model with its humble alloy frame, but that doesn't mean it's unsophisticated. The various touring-friendly mounts are complimented by internally-routed cables that help a lot when strapping on frame bags or cages, as well as keeping them generally out of harm's way. I did find several of the bungs protecting the mounting/cable holes disappeared overboard on rough trails though, so if you want to keep filth out of your threads/frame you might want to stock up – or wind in some actual bolts where you can.

Components and build

Trek has spent the budget wisely here, speccing the excellent Shimano GRX shifters, levers and hydraulic brakes. The flat-fronted levers are particularly good for grip when it's rough, the shifts are always positive and the two-piston calipers are powerful and easy to modulate on the 160mm discs. Basically, the whole stop and go thing is covered perfectly.

Well, almost perfectly. The 2x11 drivetrain gives a very useable spread of ratios, but for the most serious off-road climbing it's a little high. At the top end it's good for 35mph before you spin out, which is great for the road and fireroad descents, but leaves the lowest gear (30/34t) slightly high for the steepest, techiest climbs. That's especially true if the bike's loaded up.

That's the lowest combination of ratios that will fit, though, so your options there are either to keep the bike as light as possible, fit a 1x crank and lose a fair bit of top speed, or get stronger...

The finishing kit is all in-house Bontrager stuff, and while it's all perfectly good they're pretty easy targets for weight loss upgrades. The Bontrager Elite Gravel bar is 44cm wide on this frame size with a good flare to the drops for extra leverage, and the comfy GRX hoods tilt inwards just enough to encourage a slightly elbows-out stance that's good for control.

The wheels – Switch hubs, 21mm wide Paradigm rims (the SL version on one end, presumably the front) and 24 spokes on each – are similarly utilitarian, being strong, middling for weight and entirely decent for the job. Wearing Aeolus XXX rim strips they're tubeless ready, and so are the Bontrager GR1 Team Issue tires, which is nice – in fact, Trek lists 6oz of its TLR sealant as a 'tire part,' so presumably consumer bikes are supplied already set, just as our test bike was.

The tires are predictable and confidence inspiring on the unusually dry terrain of our test period, as well as on tarmac both damp or dry, but are clearly not designed for mud. There's room in the frame for up to 45mm rubber should you want to go wider.

Oh, and while the front axle looks like you'll need to carry a hex key to get it out, the lever on the rear thru-axle actually pulls out to fit in either one. 

Performance

The Checkpoint has a confident feel – its length and reasonable heft keep it planted, while the steering is stable without being sluggish. It's the same whether you're on gravel or tarmac, and predictable in a friendly but not boring way. The chunky headtube and sizeable welded junctions do a great job of keeping it tracking where it's pointed in the rough.

Despite the chunky, almost box-section seatstays and generally rigid-feeling frame, it's comfortable for long rides, thanks to the high volume tyres, well-cushioned bar tape and a supportive, hammocky P3 Verse Comp saddle you really sit 'in'.

Get up some speed on gravel though and there's no disguising the aluminum build. By 30mph on a fireroad, your hands and feet are taking some serious vibes, and the chatter from sustained speed does reduce comfort. 

Switching to carbon at the bar (and at the Bontrager seatpost) would both increase comfort and reduce weight, and though I found the saddle supportive and comfy both for long rides and hard pedaling efforts, it does have steel rails – it's another easy and relatively cheap target for weight loss and vibe reduction.

Alternatively, if you want more speed whatever the trails do, fit the best dropper post that will suit the 27.2mm seat tube and reap the rewards.

Personally, I would have quite liked the shorter cranks of the smaller sizes instead of the 175mm GRX RX600s fitted here, which would allow an even lower BB for descending confidence, but that's really just preference. The 7.4cm BB drop is pretty low in the scheme of things, cornering feel is predictable, and ground clearance is good.

This is an extremely usable yet still very enjoyable bike. It nails that '2/3rds road bike, 1/3rd XC bike' feel that makes gravel bikes so good for so many things – commuting while avoiding the worst traffic, touring, exploring dilapidated rural lanes, getting in hard climbing efforts away from ANY traffic, or just generally getting out there and enjoying the view. 

It's comfortable and reassuring from the off whatever the surface, and the money's been spent in the right places – this is a really solid base for years of riding fun.

2023 Trek Checkpoint ALR 5 Driftless Review

Are you searching for an endurance gravel bike that combines lightweight performance and severe loyalty to the cause? If so, the 2023 Trek Checkpoint ALR 5 Driftless may be the perfect choice for you.

The latest version of the Check Point ALR 5 is a future-proofed long-distance gravel bike that has been heavily developed over several years. 

It features an all-new lightweight Alpha Aluminum frame and some seriously impressive technology, flat mount brakes, hidden fender mounts, and even a small frame bag.

All of this comes together to create an agile, long distance experience that packs in comfort without compromising on speed and control. 

In this review we take a closer look at what makes the 2023 Trek Checkpoint ALR 5 Driftless so special and why it could be one of the best options available on the market today.

The 2023 Trek Checkpoint ALR 5 Driftless was released recently and the anticipation for the bike has been huge. 

This high-performance all-road gravel bike offers a lightweight, responsive package that is built for long rides and intense races. 

Built with an aluminum frame and carbon fork, this Checkpoint comes packed with features like an 11-speed Shimano drivetrain and hydraulic brakes. 

In this review, we’ll be taking an in-depth look at the 2023 Trek Checkpoint ALR 5 Driftless and seeing how it performs on the trail.

Frame Design

The Trek Checkpoint ALR 5 Driftless features an aluminum alloy frame that is designed to offer good power transfer while remaining light weight. 

The frame has clearance for 700x45c or 650×2.1″ tires, allowing you to take on more challenging road surfaces with confidence. 

The frame also uses Trek’s Control Freak internal cable routing system which helps to streamline the design by tucking away all of the cables inside of the frame.

Groupset and Components

This version of the Checkpoint ALR 5 Driftless comes equipped with a Shimano GRX 11-speed groupset which includes a shifter/brake lever combo, front/rear derailleurs and a 11-42t cassette. 

When it comes to braking, this bike features flat mount hydraulic disc brakes from Shimano which offer reliable stopping power even on wet or muddy roads. 

As for suspension, this Checkpoint model uses a rigid carbon fork to provide some comfort without taking too much away from its agile feel.

The wheels on this model are Bontrager Paradigm tubeless compatible wrapped with Bontrager GR2 Team Issue Elite 700x40c tires. 

These rims are strong and light, making them ideal for gravel riding where speed changes frequently and terrain can get rough or technical at times. 

They even include a small bottle of tubeless sealant should you choose to run them tubeless.

Overall Ride Feel

As far as ride feel goes, this Trek Checkpoint ALR 5 Driftless has a stiff and snappy feel thanks to its lightweight construction and rigid carbon fork design. 

The geometry of this bike helps foster good power transfer throughout pedal strokes while still allowing you to stay agile around tight corners or when navigating through technical terrain at higher speeds. 

With its dependable components like Shimano’s GRX 11-speed groupset and hydraulic disc brakes you get great performance in any condition whether you’re racing against your friends or just out exploring some local trails.

Road Test: Trek Checkpoint ALR5 Driftless

This article first appeared in the July/August 2023 issue of Adventure Cyclist magazine.

The Driftless is a special edition of Trek’s Checkpoint gravel bike, and its moniker refers to the Driftless Area of the Midwest — specifically Wisconsin, Trek’s home state. Thanks to the internet, I now know that the Driftless Area was never covered by ice during the last ice age and therefore lacks glacial silt deposits, known as drift. Elsewhere in the Midwest, receding glaciers flattened the landscape; not so in the Driftless, where you’ll find steep hills and deep, narrow river valleys.

Trek’s Checkpoint is available in several iterations in carbon or aluminum and 1x or 2x drivetrains. The Driftless, however, comes in only one spec, but it’s a good one: aluminum frame, carbon fork, 1x drivetrain, dropper post, and bolt-on half framebag. The Driftless is also available in only one color, a dark red that Trek calls — wait for it — Satin Cobra Blood . If that didn’t come out of an ayahuasca fever dream, I don’t know what would. But look closely at the paint and you’ll see topographical lines that, according to Trek, evoke the Driftless Area. It’s a sharp-looking bike. And when you open the framebag, you’ll see the red topo pattern repeated on the interior fabric. That deserves a chef’s kiss right there.

The Driftless comes out of the gate ready for loaded adventures, featuring rack and fender mounts, four bottle mounts, triple mounts on the fork, and mounts for a top tube bag. With the framebag installed on the size 56cm I tested, I was able to fit a small bottle on the seat tube and a large bottle on the downtube. The framebag’s main compartment features three pockets, which is great for keeping things like your phone, wallet, keys, and a multitool handy without bouncing around. If you want to carry more water bottles, you can always remove the framebag to take advantage of the upper downtube bottle position: the inner triangle can carry up to three bottles.

For the drivetrain and brakes, Trek chose high-end Shimano GRX bits, which provided crisp shifting and easy, one-finger braking. With no front derailer, the left shifter is available to actuate the dropper post, a feature I absolutely loved. But with a 40T chainring and an 11–42T cassette, the Driftless had less gearing than I would prefer, especially on a bike named for a region with steep hills and with designs on loaded riding. The Easton dropper post provided only 50mm of travel, which for a bike like this is plenty. It’s just enough to lower your center of gravity but not so much that you can’t still get a few pedal strokes in.

As for the rest of the spec list, it’s a lot of Bontrager-branded stuff that worked quite well. I liked the shape and feel of the handlebar with its 13° flare, but I found the 420mm width a tad narrow. Likewise, the Bontrager wheels rolled just fine, but with only 24 spokes per wheel, they might not be ideal if you plan on really loading this bike up. The GR2 tires rolled quickly on pavement and provided a ton of grip on dirt, and they managed to survive the sharp rocks and scattered broken glass here in Salt Lake City, which is no small feat.

So aside from a cool paint job, a nifty framebag, and a dropper post, it’s just a gravel bike, right? Wrong. Somehow, the Wisconsin brand has created one of the most fun bikes I’ve ever thrown a leg over. The Driftless was screamingly quick on the road, even with its off-road tires — I quickly realized that being able to drop my butt 50mm on canyon descents makes me go much, much faster and with way more confidence — and with its short wheelbase and steep-ish head angle, it was an absolute riot on dirt, especially singletrack. A term we don’t often use in this publication is tossable , as in maneuverable, twitchy. With the slightest input, I could snake this bike around rocks and drift around corners like a hooligan. On one of the most fun days I’ve ever had on a bike, I rode the Driftless 20 miles on pavement to a trailhead, rode 20 miles of singletrack on green and blue mountain bike trails, and then rode 20 miles of pavement home. I couldn’t feel my legs the next day, but it was worth it.

So what’s this bike’s special sauce? I have no idea. The bike felt short and twitchy and pointy , as we say in the mountain bike world, but it was also surprisingly compliant. Something I’ve come to learn recently is that manufacturers have figured out how to make aluminum frames that don’t beat you up, and the Driftless is one such bike. But I also think the carbon fork and the low spoke count of the wheels played a role in the ride feel as well. Without isolating the various factors, it’s hard to point a finger at the source. But I tend to think that Trek hit upon a magical combination, and I’d be wary of replacing any one thing for fear of compromising this bike’s unique qualities.

The New Trek Checkpoint Line Is For Gravel Riders of All Kinds

Updated geometry and differentiated models for speed, adventure, and all purpose riding

The Takeaway: A great bike gets better, with geometry updates suited to the evolution of gravel.

• Two centimeters longer reach and front center on all sizes
• One centimeter longer chainstays
• New race-oriented SLR platform
• Additional cargo mounts

Price: $12,000 (SLR 9, as tested) Weight: 17.8 lb. (Size 54cm)

Trek’s gravel loving Checkpoint is all new front to rear, with new geometry (covered below) and features for the ever-evolving world of gravel riding. That evolution is why Trek differentiated the three complete bike platforms—SLR, SL, and ALR—for different kinds of gravel riders. I go into more depth below, but the short version is: SLR = race; SL = all-around, ALR = utility.

Threaded T47 bottom brackets now grace all Checkpoint frames, but Trek has done away with the sliding dropouts found on the previous generation Checkpoint. All eight builds get gravel gearing and clutch-style rear derailleurs (Shimano GRX or SRAM eTap AXS), as well as 40mm tubeless ready tires and tubeless ready rims. All models, and all sizes, can fit up to 45mm tires with plenty of mud clearance; which means riders in dry conditions can fit in even bigger tires. If you choose, you can fit the Checkpoint with 650b wheels—all models and all sizes come stock with 700c wheels—which bumps tire clearance up to 53mm (2.1 inches).

In the press release, Trek makes mention of “ Émonda -inspired aero tube shapes,” without providing any wind tunnel data. My suspicion is the tube shapes do save a few watts, though Trek isn’t leaning into gravel aero as much as 3T does with its Exploro RaceMax .

Trek Checkpoint — Geometry

Geometry is where the new Checkpoint sees the biggest change. While there are three Checkpoint frame platforms (outlined below), all three share the same, all new, geometry (see table above).

The overall theme to the geometry updates is “more progressive.” Trek took a page from the mountain bike playbook and stretched all sizes of the frame’s reach and front center by about two centimeters. Trek now fits shorter stems and shorter-reach bars to mitigate cockpit length changes. Chainstays on the frame grow by a centimeter (now 435mm on all sizes). Trail is also longer (about six millimeters) even though head angles remain about the same—new fork offset is 45mm, old was 49mm—and wheelbase grows as well. Frame stack bumps up a touch too.

Jordan Roessingh, Trek’s director of road product, says the new geometry aids stability, “It’s a longer bike, so whether you’re doing long Unbound type stuff where you’re just pointing the bike straight or you’re doing high speed stuff on gravel descents in the mountains, we believe this geometry lends itself to confidence. Getting that wheel out in front of you also unweights it makes you feel a lot more confident when you’re doing steep technical stuff—you don’t feel like you’re going to go over the bar. That front wheel is really easy to unweight and allows it to roll over a lot more stuff.”

Roessingh further explained that the new geometry also reduces toe overlap on smaller sizes and allows them to approve larger tires sizes for smaller riders, “On the previous [Checkpoint] we had to limit our small frame size tire size recommendations to only 40mm. Not because the frame didn’t have the capacity for 45, but when you put a 45 it created too much toe overlap.” The issue here was government regulations that outline a production bike’s maximum tire overlap. But with the new bike’s longer front end every size can, officially, run up to a 45mm tire.

One note on the geometry: The new Checkpoint is not suspension fork corrected. However, the Checkpoint has a 1.5-inch lower fork steerer diameter, so you can fit the new RockShox Rudy , a Suntour GVX, or Fox AX, but doing so will raise the front end and slacken its angles.

Trek Checkpoint — Where is the Front IsoSpeed?

One surprising omission from the new Checkpoint is IsoSpeed in the front, a feature found in Trek’s Domane all road bikes . According to Roessingh, IsoSpeed on the front of a bike with big tires, “Doesn’t provide a sufficient gain in compliance to make a real difference to the rider because a [larger than 32mm tire] is such a dominant aspect of the compliance,” so it was left off the new Checkpoint. The benefit is a less complicated front end, and some weight savings.

Rear IsoSpeed continues on all models. Roessingh explains that it has more deflection than front Isospeed so it offers additional compliance benefit even with larger tires.

Trek Checkpoint — Three Frame Platforms

The new Checkpoint comes in three platforms: SLR, SL, and ALR. The top of the line SLR (super light race) platform is new to the Checkpoint line. Previously, Checkpoint topped out with the SL model. All the models have T47 threaded bottom bracket, internal hose and housing routing, 45mm tire clearance, frame bag mounts, fender mounts, and come in six sizes: 49 to 61cm. SLR and SL carbon frames get the same in-frame storage system found on carbon Domane frames.

But though the three platforms share geometry and many features, they’re tuned to suit different riders.

The SLR is race oriented, so it gets the highest-grade carbon composite, a traditionally shaped (not flared) road bar, and forgoes cargo mounts on the fork. This model also has Trek’s no-cut seat mast with (non-adjustable) top tube IsoSpeed.

The SL gets an all-purpose gravel focus. It uses lower grade carbon than the SLR but adds adventure riding features like three-pack mounts on the fork legs, and a flared gravel bar. This model does have Trek’s IsoSpeed decoupler in the seat tube but fits a traditional 27.2mm seatpost: That makes this model dropper-post compatible.

The aluminum framed ALR is the least expensive of the new Checkpoints, and Trek’s representatives expect this to be a popular model with riders looking for a commuter or utility bike. It has the same geometry as the other platforms, and the same rack, fender, framebag and mudguard mounts as the Checkpoint SL, and it gets a flared gravel bar and 27.2mm dropper-post compatibility. The two features it lacks relative to the SL are the in-frame storage and an IsoSpeed decoupler.

Trek Checkpoint — Models, Prices, Weights

There are eight complete bikes for the USA: one ALR, three SL, and four SLR models. Prices and claimed weights are below, with a quick look at the build kits. All complete bikes roll on Bontrager GR1 40mm tubeless ready tires, have tubeless ready rims, and ship with tubeless valves, rim strips, and sealant.

Trek Checkpoint — Ride Impressions and Review

Trek sent me the top-of-the-line SLR 9 eTap AXS well ahead of the bike's launch, and I’ve done my usual “gravel” shenanigans on this bike—long gravel rides, mixed media rides, some road riding, and plenty of singletrack.

On anything dirt, and especially on singletrack, the new Checkpoint is not just better than the previous generation, it’s one of the best gravel bikes I’ve been on. I love the previous generations above-average comfort and smoothness and that’s still present, but the geometry updates make the new bike much more capable: And the faster and more technical the dirt, the more the geometry pays off. It’s accurate, but not darty, and composed but appropriately flickable.

Here’s the rub: Give us geometry that lets us go faster and…we’re going to go faster. The Checkpoint is so damn fast on downhills singletrack that I take issue with Trek’s decision to forgo front IsoSpeed or correct the geometry for a suspension fork. I mean, this is a pretty compliant bike overall, but when you go faster the hits get stronger. Many times I wacked stuff that made my hands and arms stung. Bigger tires help, but a 45mm maximum isn’t that big (Canyon’s Grizl fits 50s, for example).

Basically, there were times I felt like the geometry was writing checks the Checkpoint couldn’t cash without some help from suspension. But then, when you add weighty suspension and fatter tires, you have a much different bike; so I’m also not sure that’s the answer. I think we’re at a very interesting point with “progressive” gravel bikes where they are tickling the edges of mountain bike capability and, if they go much further, suspension must be a part of the conversation.

On the flip side of the new Checkpoint’s added capability, it feels less chipper on paved surfaces. The old Checkpoint was almost a road bike that could do gravel while the new one definitely takes cues from the world of mountain bikes. On balance, this works out okay for the most fun and challenging parts of gravel rides, though the Checkpoint bike feels a bit logy on the liaisons between the best bits. That’s a compromise I’m okay with, but if you want more quickness on pavement from your gravel bike you might be happier on something like a Cervelo Aspero 5 or the 3T Exploro Racemax .

Trek isn’t breaking any new ground with the Checkpoint’s geometry and handing traits. This mountain bike influenced longer, more stable, geometry (oh, hello, Chamois Hagar ) is an increasingly popular trend, and already found in bikes like Canyon’s Grizl (which the Checkpoint reminds me of) and some other bikes. I’m curious to see how this geometry goes down with the general riding public, and how far brands push the geometry. When used for actual gravel and off-pavement riding and racing, this geometry makes sense. But if riders are buying gravel bikes because they want more capability and comfort out of a drop bar bike, but are mostly sticking to pavement, I don’t think this geometry suits that kind of rider.

Handling covered, let’s look at the rest of the Checkpoint’s attributes. The added cargo options (in frame storage, direct mount bag in main triangle) are great, almost mandatory, features for a gravel bike. My 54cm frame did have two water bottle mounts on the downtube, but it required a bit of trial and error with a Wolf Tooth B-Rad base to get two bottles to fit comfortably. With the Bontrager frame bag mounted, I needed to reposition the seat tube cage location to fit a bottle. Larger sizes have more space in the main triangle, so this won’t be an issue, but riders on frames smaller than 54 might need to look into alternative ways to carry water if they run the frame bag.

I do have a gripe with the road-bend bar on the SLR models. Trek sees this model as appealing to racers who are coming from a road background. This is why it gets a traditional, and lighter, road bar. But it’s still a gravel bike, and flared drops are awesome for comfort and control. Besides, flared bars are so awesome that once you ride them, you’ll want to put them on your road bikes. Thankfully, Trek didn’t do anything weird with the bar and stem on the new Checkpoint, so riders can fit anything they desire.

That’s my only gripe though. I love this bike, and the rest of the parts kit is dialed. I’m going to throw out special kudos for spec'ing the SRAM-equipped SLR models with power meters from the factory. I think that’s perfectly in line with this bikes purpose and customer.

Overall, the new Checkpoint is a wonderful gravel bike. It’s faster, better handling, and more suited to the needs of the today’s gravel rider.

2022 Trek Checkpoint ALR 5 Review

Garret seacat, c.s.c.s..

Reviewing the all-new 2022 Trek Checkpoint ALR 5

The 2022 Trek Checkpoint ALR 5 is a welcomed update to an already successful line of gravel bikes from Trek. As a long-time cycling coach and native of the Flint Hills of Kansas, we didn’t hold back on our Trek Checkpoint ALR 5 review. 

2022 Trek Checkpoint ALR 5

• Lighter frame than the previous version
• Nicely equipped components.
• Feels quick and nimble even with the long-wheelbase
• Updated geometry
• Lifetime Warranty
• We don’t mind but the removal of sliding dropouts
• Not as relaxed geometry as Trek Domane making it more of a race bike than a relax gravel bike

First Impressions

The Checkpoint needs almost no introduction to most riders familiar with the gravel scene but this year brought along an update to the already popular bike. While you could spend big money and go for the incredibly well-equipped and lightweight SLR model, we decided to stay more modest and review a more humble ALR 5 that will likely find its way into your garage.

Before we get too far, I want to mention I am VERY familiar with the Checkpoint, and this is the 4th different one I’ve owned. And well before that, I was part of a bike shop that helped contribute and give input on the “new gravel” bike from Trek, or what we would later learn was the first version of the Checkpoint. I sold my 2020 SL after just deciding it wasn’t the right fit for me, but here I am again with another Checkpoint added to the stable of bikes.

Straight out of the box, I was impressed with how light it was, even with all the stock components at the time. Also, the updated paint schemes on all the models are gorgeous in person! However, I quickly realized while assembling the bike my taste for carbon would likely result in some upgrades reasonably quickly to help lighten the bike even more and improve the feel. More on that later.

Riding the Checkpoint

It wouldn’t be a Checkpoint ALR 5 review without putting it on the gravel in Kansas, and luckily that’s exactly where we are located. While you miss out on the Iso-Speed of higher-end carbon Checkpoints, you won’t notice it much. Having ridden a variety of carbon Trek bikes with Iso-Speed, I was pleasantly surprised at the ride quality of the ALR. To help take the edge off, I added an RSL seatpost, and then the bike came to match the ride quality of much more expensive bikes.

On the same idea of changing things, take the stock tires ASAP. They aren’t that good! They roll fast, but you will flat in no time and ruin that new bike experience.

After a quick 20-mile break-in ride with stock parts, I changed the wheels to a pair of Bontrager RSL 37V and changed the seatpost and stem to Bontrager RSL carbon bits. I also put a wider 44cm width bar on. Is this necessary? Absolutely not, but the bike really comes alive!

One note on the geometry, it feels great but is noticeably different than the previous model. While the effective top tube says it is longer it felt shorter! The wheelbase also got shortened this year but has more front toe clearance and a similar chainstay length to previous years.

Since putting this bike together, I have almost shelved my carbon bikes completely. I even went to a couple of gravel races and left the carbon race bike at home because I enjoy the new Checkpoint ALR 5 that much! The best part is having riders come over and pick it up and their shock when I tell them how much I have invested in it compared to what they have spent.

Final Thoughts

At $2500 retail, you cannot go wrong with the Checkpoint ALR 5. It is just a all around fun bike to ride. The stock Shimano GRX R600 and R800 components and tubeless-ready wheels will have you ready for whatever you want. If you can swing it, grab a carbon seat post, I recommend the Bontrager RSL for the “flex” to help take a little more out of the gravel.

If you can find a shop with an ALR 5 in stock then give it a ride and don’t think twice about taking it home if it fits!

Rating (4.6/5)

Introduction

Do you like epic off-road adventures? End with a burger and beer shuttle burrito from Texaco for a well-deserved off-road adventure. If you can get preferred adventure options for every dollar you spend, then the Trek Checkpoint ALR 5 would be the perfect fit. Quality parts, a durable alloy frame, and plenty of features like extra tire clearance make for a quality riding experience.

The 2×11 Shimano GRX  is an unbeatable conqueror of steep hills and rough gravel surfaces. Not only that, but the flexible and stable progressive geometry lets you find the right angle travel angle on different surfaces. Whether it’s sidewalk and dirt or grass sections, the 700x40c gravel tires grip the ground consistently. The extreme stability and traction guarantee you stronger, farther, and longer distances.

We’ve had two months of experience measuring the Trek Checkpoint ALR 5, and to make the results more informative for you, we’ll elaborate on the Trek Checkpoint ALR 5’s performance while riding, key features, components and specifications, and other versions of the series. If you’d like to see more versions, please refer to our review.

General Riding

Our team chose a flat and tidy road for our two-week test. This may not be a big challenge for Trek Checkpoint ALR 5. The Trek Checkpoint ALR 5 is also designed to be the most comfortable for the public. Its 53.8mm stack has been tested extensively to fit the public as much as possible.

I chose the m model and it was easy for me to straddle the body and maintain an upright and stable seating position. The new progressive geometry allows for fast, agile handling and keeps me stable and in control on rough descents.

I have to admit that the 300 series alpha aluminum is my ideal quality frame. Also, the hydroformed tubes allow me to maintain a relatively stable body condition. It has a durable life at a great price. This is good news for the price party.

I’ve always had high expectations of the Shimano brand, and the Trek Checkpoint ALR 5 with the Shimano GRX RX600 continues to perform well, providing great traction even on slippery bermed roads. When I switched from flat roads to gravel roads, all I had to do was move the paddles at hand to shift gears. But the downside is that the 2x series takes more time to shift. Maybe the Trek Checkpoint ALR 5 can try the Shimano 1x system in the next revision. I don’t mind the extra upsell price either.

Not only that, but I have to admit that the Bontrager GR1 was a reliable help in my travels, and the 700x45c size specification is perhaps not a very large and generous presence. But with the front and rear wheelbase of 1033mm, it gave me more responsive steering, and I was able to control the body well and drift at great speed in the many sharp turning areas in the line. What was clear was the rustle of tires colliding sharply with the ground. Yes, it was pretty crazy.

Long-Distance Riding

As the main battleground for gravel roads, the Trek Checkpoint ALR 5 performed amazingly well. We chose a practice course dedicated to off-road road biking, which included sidewalks, dirt, and even the most complex gravel surfaces.

The GRX  is the anchor for the ride and I can travel at a very fast speed. Having a stable paddle makes the ride more reliable, even when the hills are full of debris and dead branches. Both the smooth, silky shifts and its rich, dense gear ratios provide fast, seamless shifts that are quiet and stable enough.

One thing that must be mentioned is that the Trek Checkpoint ALR 5 accommodates the setup and it is your most loyal and reliable companion on long trips. The integrated frame bag and fender mounts make it easy to carry gear and water and essentials for the trip. During the final kilometer sprint, I could noticeably feel more bumps on the gravel road. But I firmly believe that the Bontrager GR1 wheelset is capable of handling such road conditions.

The TLR tubeless setup allows for the tire pressure I get in the middle of a run to increase traction and comfort. A special anti-puncture system ensures that the Bontrager GR1 wheelset will maintain a strong surface without the risk of blowouts. Meanwhile, Trek’s new flush-mounted disc brakes offer advantages over traditional mechanical braking. The lighter and smaller size allows me to keep maintain the ultimate body stability. I was also able to apply full emergency braking when driving on wet, muddy roads without creating more forward movement. This is something that makes me marvel at the power of Trek’s craftsmanship.

Main F eatures

I have to admit, the Trek Checkpoint ALR 5 will have a lot of details that are well thought out. The Trek Checkpoint ALR 5 keeps more color options including Era White / Trek Black; Satin Nautical Navy / Satin Red. Alpha Aluminum material is also the most cost-effective choice. The 300 series alpha aluminum material is the most cost-effective choice, maintaining a high level of performance at a lighter weight. Of course, in terms of cost-effectiveness, it is also the most affordable.

The Bontrager mixer stem allows you to clip on the equipment directly to the stem for a clean look, complete with internal alignment to maintain a clean heading. You won’t have to agonize over annoying cables. The new progressive geometry is the best feature of the Trek Checkpoint ALR 5. You can choose the right modification for your needs. You can add water bottles to both the top tube and the seat tube. And the integrated frame bag and fender mount make it easy to carry your gear.

The geometry of the Trek Checkpoint ALR 5 does not disappoint the user. 73.7° seat tube angle is not an extreme setting. This not only takes into account the need for traction when ascending but also the need to maintain a comfortable seating position when descending in the first place.

The 1033mm wheelbase may not be a common presence for some people, so they may worry about losing control of the steering. Of course, many months of riding experience will tell you that there is no need for such anxiety. Don’t forget that the Bontrager GR1 is set up with a wider (700x45mm or 27.5×2.1) tire surface that allows you to handle thick gravel terrain. The lower BB center of gravity of 271mm also allows you to maintain stability while making agile steering.

Component s   and Specifications

Shimano grx rx x600 11-speed drivetrain.

Some people may think that the 2× speed change is more complicated to operate, so I asked a rider who is not very experienced to experience it. He told us that the Trek Checkpoint ALR 2× didn’t feel any different from the 1×. This may not make a big difference to a novice rider. But if you’re a pro like us, it’s probably not a good choice. Because personally, it’s too complicated. When I went from a smooth road to rough grass, it did take a lot of time to shift gears.

Shimano SM-RT70 Brake

The Shimano SM-RT70 is probably a good choice for every road ride. The 3-layer construction, an aluminum core, and two stainless steel outer layers reduce the rotor surface temperature by about 100 degrees Celsius compared to an all-steel rotor. It’s not as heavy as you might think, so it doesn’t put much of a damper on travel. Of course, it features a new brake track vent design for smooth, quiet braking performance. When I encounter an emergency and have to make an emergency stop, I can brake by simply pressing the control on the handlebars. In addition, the convenient and simple fuel line connection system makes my installation and adjustment process much easier and more convenient.

Bontrager TLR Sealant Tires

I have to admit that the Bontrager line of tires is still one of the most popular products among cyclists. The most distinctive feature is the flat protection seal, the latest Bontrager offering, and the slim 700x40c tire width gave me the first impression that it might perform better on asphalt. But as I rode over bumpy gravel singletrack trails, I found the tire’s grip to be commendable. Also, the puncture-resistant special material allows you to fight against sharp branches and gravel without fear.

Other versions of Trek Checkpoint ALR 5

To give you more possibilities in your choice, we tested other models of Trek Checkpoint ALR objectively and impartially and for a certain period.

These include the Trek Checkpoint ALR 5 Driftless and the Trek Checkpoint SLR 5.

Trek Checkpoint ALR 5 Driftless

To be honest, the Trek Checkpoint ALR 5 Driftless is not much different in terms of materials and construction. 300 series alpha aluminum is equipped with 700c tires, keeping it stable and light at the same time (Trek Checkpoint ALR weighs 21.5 lbs, Trek Checkpoint ALR 5 Driftless 21.2 lbs. Checkpoint ALR 5 Driftless is 21.2 pounds).

But the difference is that the Trek Checkpoint ALR 5 Driftless has received a minor drivetrain upgrade. This greatly solves the problem of complicated speed adjustments and the inability to find the right gear. This may be good news for riders who seek high performance. Although in the price you need to pay $ 400 more.

Trek Checkpoint SLR 5

Thankfully, the Trek Checkpoint SLR 5 has made significant changes to the frame. It ditches the aluminum shell in favor of a higher-quality carbon material. This also means more toughness and greater shock absorption on the road. But it’s worth noting that the cost of $3,299 is a bit steep.

In terms of other component specifications, the Trek Checkpoint SLR 5 doesn’t make too many other changes. If you are looking for a good price/performance ratio, I still think Trek Checkpoint SLR 5 is the best choice for you.

1.  What is the price of Trek Checkpoint ALR 5?

The Trek Checkpoint ALR 5 is priced at $2499.99.

2.  What is the body material of Trek Checkpoint ALR 5?

The body material of Trek Checkpoint ALR 5 is 300 Series Alpha Aluminum.

3.  What are the tire specifications for the Trek Checkpoint ALR 5?

The Trek Checkpoint ALR’s tire size is 700x45c.

4.  What is the Trek Checkpoint ALR 5?

Trek Checkpoint ALR 5 has a Shimano GRX RX x600 11-speed.

5.  How do I choose the Trek Checkpoint ALR 5 size?

Comparison Table

Trek checkpoint alr 5 vs marin headlands 1.

On top of the nearly $200 increase, the Marin Headlands are made of carbon. Simply put, the 300 series alpha aluminum will improve some toughness and damping ability compared to the Trek Checkpoint ALR 5. But it’s worth acknowledging that the 300 series alpha aluminum has achieved the peak of the alloying process.

Meanwhile, Marin Headlands used 700x44c, vee tires compared to the Trek Checkpoint ALR 5’s 700x45c to see the excellent smoothness and grip of the two played a tie.

In addition, the Marin Headlands uses the Shimano CSM8000 1×11 speed  option to keep the lighter body under the lighter drive housing. But if dealing with more complex terrain, I think the Trek Checkpoint ALR 5’s 2×11 speed has more options and also provides freer riding support.

Trek Checkpoint ALR 5 vs Trek 1120

Compared to the Trek Checkpoint ALR 5, the Trek 1120’s 31.0lbs. weight was the heaviest of all the weights tested. Despite the tire set-up, the Trek 1120 chose to roll on more efficient 29″ tires. However, the excessive weight of the body will also have a greater impact on speed during rapid driving.

However, it is worth noting that the Trek 1120’s 1×12 speed drivetrain is less complicated to operate than the Trek Checkpoint ALR 5’s 2×11 drivetrain. This allows for silky smooth shifting.

Comparing the two each has different advantages. But when you look at them all together, I think the Trek 1120 has a higher degree of fit between the various components and more extreme pursuit of speed.

Trek 1120 Review – The Road Is No Longer Far But Under Your Feet

Trek Checkpoint ALR 5 vs Framed Mallorca Disc Road Bike

The Framed Mallorca Disc Road Bike is positioned as a versatile road bike, so it is not as fast as the Trek Checkpoint ALR 5. (For reference: the Framed Mallorca Disc Road Bike is 26mph, and the Trek Checkpoint ALR 5 is 36mph.)

Due to the close price of both, hydraulic disc brakes are used for the braking options. The convenient and simple connection system makes the installation and adjustment process much easier. So in the test of an emergency stop, the two played a tie.

Also, if you notice the choice of the wheelset, the Framed Mallorca Disc Road Bike’s 700x40c size compared to the Trek Checkpoint ALR 5’s 700x45c, the narrower tires will create a drifting sensation on some muddy and slippery roads. It can’t do more stable control.

Trek Checkpoint ALR 5 vs Salsa Journeyer GRX 810 700c

Journeyer Drop-Bar thru-axle carbon is the body material of choice for the Salsa Journeyer GRX 810. Although more malleable, the Trek Checkpoint ALR 5’s 300 series slpha sluminum also takes the advantages of the alloy to the extreme. It’s light enough to rival carbon and will be more resistant to outdoor friction.

In addition, the 700 x 40C tire setup is narrower than the 700 x 45c of the Trek Checkpoint ALR 5, making it difficult to give enough stable support for extreme speeds on slippery roads. This is the biggest regret in my opinion.

In terms of choice, the Salsa Journeyer GRX 810’s 1×11 drivetrain enhances ease of operation at the expense of a wider range of speed control.

As a whole, I think the high performance of the Trek Checkpoint ALR 5 is more likely to be reflected in the ride.

Savvino-storozhevsky monastery and museum.

Zvenigorod's most famous sight is the Savvino-Storozhevsky Monastery, which was founded in 1398 by the monk Savva from the Troitse-Sergieva Lavra, at the invitation and with the support of Prince Yury Dmitrievich of Zvenigorod. Savva was later canonised as St Sabbas (Savva) of Storozhev. The monastery late flourished under the reign of Tsar Alexis, who chose the monastery as his family church and often went on pilgrimage there and made lots of donations to it. Most of the monastery’s buildings date from this time. The monastery is heavily fortified with thick walls and six towers, the most impressive of which is the Krasny Tower which also serves as the eastern entrance. The monastery was closed in 1918 and only reopened in 1995. In 1998 Patriarch Alexius II took part in a service to return the relics of St Sabbas to the monastery. Today the monastery has the status of a stauropegic monastery, which is second in status to a lavra. In addition to being a working monastery, it also holds the Zvenigorod Historical, Architectural and Art Museum.

Belfry and Neighbouring Churches

Located near the main entrance is the monastery's belfry which is perhaps the calling card of the monastery due to its uniqueness. It was built in the 1650s and the St Sergius of Radonezh’s Church was opened on the middle tier in the mid-17th century, although it was originally dedicated to the Trinity. The belfry's 35-tonne Great Bladgovestny Bell fell in 1941 and was only restored and returned in 2003. Attached to the belfry is a large refectory and the Transfiguration Church, both of which were built on the orders of Tsar Alexis in the 1650s.  

To the left of the belfry is another, smaller, refectory which is attached to the Trinity Gate-Church, which was also constructed in the 1650s on the orders of Tsar Alexis who made it his own family church. The church is elaborately decorated with colourful trims and underneath the archway is a beautiful 19th century fresco.

Nativity of Virgin Mary Cathedral

The Nativity of Virgin Mary Cathedral is the oldest building in the monastery and among the oldest buildings in the Moscow Region. It was built between 1404 and 1405 during the lifetime of St Sabbas and using the funds of Prince Yury of Zvenigorod. The white-stone cathedral is a standard four-pillar design with a single golden dome. After the death of St Sabbas he was interred in the cathedral and a new altar dedicated to him was added.

Under the reign of Tsar Alexis the cathedral was decorated with frescoes by Stepan Ryazanets, some of which remain today. Tsar Alexis also presented the cathedral with a five-tier iconostasis, the top row of icons have been preserved.

Tsaritsa's Chambers

The Nativity of Virgin Mary Cathedral is located between the Tsaritsa's Chambers of the left and the Palace of Tsar Alexis on the right. The Tsaritsa's Chambers were built in the mid-17th century for the wife of Tsar Alexey - Tsaritsa Maria Ilinichna Miloskavskaya. The design of the building is influenced by the ancient Russian architectural style. Is prettier than the Tsar's chambers opposite, being red in colour with elaborately decorated window frames and entrance.

At present the Tsaritsa's Chambers houses the Zvenigorod Historical, Architectural and Art Museum. Among its displays is an accurate recreation of the interior of a noble lady's chambers including furniture, decorations and a decorated tiled oven, and an exhibition on the history of Zvenigorod and the monastery.

Palace of Tsar Alexis

The Palace of Tsar Alexis was built in the 1650s and is now one of the best surviving examples of non-religious architecture of that era. It was built especially for Tsar Alexis who often visited the monastery on religious pilgrimages. Its most striking feature is its pretty row of nine chimney spouts which resemble towers.

The Unique Burial of a Child of Early Scythian Time at the Cemetery of Saryg-Bulun (Tuva)

<< Previous page

Pages:  379-406

In 1988, the Tuvan Archaeological Expedition (led by M. E. Kilunovskaya and V. A. Semenov) discovered a unique burial of the early Iron Age at Saryg-Bulun in Central Tuva. There are two burial mounds of the Aldy-Bel culture dated by 7th century BC. Within the barrows, which adjoined one another, forming a figure-of-eight, there were discovered 7 burials, from which a representative collection of artifacts was recovered. Burial 5 was the most unique, it was found in a coffin made of a larch trunk, with a tightly closed lid. Due to the preservative properties of larch and lack of air access, the coffin contained a well-preserved mummy of a child with an accompanying set of grave goods. The interred individual retained the skin on his face and had a leather headdress painted with red pigment and a coat, sewn from jerboa fur. The coat was belted with a leather belt with bronze ornaments and buckles. Besides that, a leather quiver with arrows with the shafts decorated with painted ornaments, fully preserved battle pick and a bow were buried in the coffin. Unexpectedly, the full-genomic analysis, showed that the individual was female. This fact opens a new aspect in the study of the social history of the Scythian society and perhaps brings us back to the myth of the Amazons, discussed by Herodotus. Of course, this discovery is unique in its preservation for the Scythian culture of Tuva and requires careful study and conservation.
