Reviewed: Trek Superfly 9.7 mountain bike

The superfly 9.7’s biggest selling point is its frame, and though the parts are modest, it has potential.

It’s easy to look at this bike and imagine an old Gary Fisher logo in place of Trek’s mark. I mean that as the highest compliment.

Quibble all you like about who invented the mountain bike. One thing’s certain: Gary Fisher played a huge role in popularizing 29” wheels, now the must-have size in nearly any off-road discipline.

His experience with his own brand, which is now rolled into Trek’s lineup, is apparent, giving this simple, middle-of-the-road hardtail an excellent personality.

Most mountain bikers need at least a couple hands to count the number of parts they break or replace any given season, but the frame is usually a constant. That is the Superfly 9.7’s biggest selling point, and though the parts are modest, it has real potential.

A fine frame

Trek doesn’t specify the particulars of their carbon construction, aside from claims that it’s thoroughly designed and tested to be used in an off-road frame.

Talk all you like about carbon, but the geometry is really what makes the Superfly sing. As soon as I hopped aboard the bike, its West coast heritage slapped me in the face like a wave off the Marin headlands.

In a few words, the 9.7 is long, low, slack, and fun. Having ridden some 29ers with 70-degree-plus head tube angles, our medium tester’s 69.3 degrees was comfortable and confident. For comparison, the Specialized Stumpjumper HT line has a 71.5-degree head angle. Trek also insists on a custom-offset fork to complete its G2 geometry.

The Superfly’s top tube length and reach are slightly longer than the Stumpjumper’s, and both lines have the same chainstay length — 435mm. It seems that the Trek gets most of its 1,160mm wheel base from the slacker head tube, making it 88mm longer than the Stumpjumper.

Interestingly, the Superfly’s bottom bracket drop is 5.5mm less than the Stumpjumper, meaning that the pedals sit slightly higher in the frame.

Aside from that detail, Trek’s bike is a longer, slacker machine than most ordinary cross-country race bikes.

Passable parts

To be charitable, the 9.7’s components are adequate. I’ve often found SRAM’s lower-end mountain bike shifting to be a bit clunky and slow to respond, and this pairing of X7 shifters and an X9 rear derailleur is no different. Trek does deserve credit for speccing a Type 2 rear derailleur with a clutch to eliminate nearly all chain noise.

The wheels are also humble — Bontrager rims and blue anodized hubs, which may not stand the test of time from a fashion standpoint. The cartridge bearing internals, however, are reassuring. The wheels are tubeless-ready, which is an essential upgrade, so it’s nice that the Trek is ready for it.

I’ll come right out and say that all 29er hardtails should have 100mm travel forks. Yes, the Fox Float 32 on the 9.7 was equipped with the Evolution damper, which is noticeably inferior to the higher-end FIT damping. But the extra cushion goes a long way to taming rough trail. The CTD lever was helpful to provide a firm ride on paved climbs, but I’d trade that for a damper that supports the middle of the travel any day. I’d lower the pressure to get top-end suppleness, only to be punished by excess brake dive and overly linear stroke.

Shimano SLX disc brakes are one of the finest aspects of this bike’s build. It’s remarkable how Shimano can deliver basic, affordable brakes like these, which are within striking distance of its XTR models.

Unfortunately, our Shimano HG62 cassette did not do as well. I destroyed it by somehow shifting the chain between the third and fourth largest cogs. It may have been a freak occurrence. It was certainly the first time for this unlucky tester.

Am I being too critical of the components? At $3,150, the Superfly 9.7 is certainly not targeted as an entry-level model. This is the type of bike a junior or collegiate racer would buy to enjoy for many years of pinning on plates. Surely they deserve a more reliable drivetrain and a capable fork.

The wheels are an easy upgrade that almost any racer expects to make. I did so myself with this test bike, improving the ride with some ENVE M50s. The faster acceleration and surefooted steering was an improvement. Those wheels also shaved a pound off the Superfly’s 25-pound stock weight. However, the most noticeable way to improve the bike’s feel is to convert the tires to tubeless, a much less expensive alternative to carbon wheels.

Another upgrade I made was a Stages power meter, which is becoming an essential training tool, even for mountain bike racers.

Taking it to the trail

Performance on paper doesn’t always equate to performance on dirt, and in some ways, the 9.7 makes that point.

I forgot about its hefty (for a hardtail) weight once it started snapping through corners and pumping fast rollers. As I’ve alluded to, the geometry gives this bike a great personality on the trail, letting you open things up on fast descents, keeping your body weight back just far enough on the steeps, and somehow avoiding any 29er sluggishness.

It’s rare to find a cross-country bike as playful as this, but the Superfly was happy to pop off jumps and whip around berms. Once terrain got rougher, things became a little less cheerful, especially with the fork’s shortcomings, but the bike loyally stayed on line. Perhaps that’s a testament to the carbon construction, as well as the 142x12mm rear thru-axle.

Once the fun ended and the work began, the Superfly was capable. It responded well as I hammered out of corners on steep climbs, rarely betraying its weight. I also enjoyed the fairly rangy top tube in the races I did. It encouraged me to stretch out a bit more, also helping to keep weight over the front wheel on steep pitches.

Is it super enough for you?

When it comes to high-speed riding and racing, the Superfly 9.7 is pretty hard to beat. You can overcome its components’ shortcomings with a few key upgrades, but you might be better off spending an extra $730 to get the 9.8 model.

However, if your riding and racing happens primarily in a place like New England where the corners, rock gardens, trees, and competition are all very tight, make sure to get a test ride on the Superfly. Its laid-back west coast personality is great in many settings, but it might not be sharp enough for every course.

Price: $3,150 Weight: 25 pounds Pros: Fun, comfortable geometry and personality. Great frame construction, reliable brakes. Cons: Underwhelming shifting and fork. Might not handle quickly enough for certain tastes. trekbikes.com

Trek Superfly Pro 29er review

Trek's flagship big-wheeled race hardtail lightens up for 2012

James Huang/Future Publishing

James Huang

The 2012 Trek Superfly Pro builds on the success of last year's Superfly Elite carbon 29er hardtail, adding an upgraded spec that lops a full pound off the build plus a through-axle and better tires that improve its overall usability. It's speedier and more fun to ride than before but that extra performance carries with it a hefty price premium.

Ride & handling: Excellent G2 geometry, stiff all around

The 2012 Superfly Pro essentially wears the same frame as last year's Elite so, not surprisingly, our list of likes and dislikes carries over, too. Handling is once again especially sweet, given Bontrager's trick G2 fork crown offset and its resultant trail, which mimics that of a 26in bike and generates a particularly light feel up front for a big-wheeler. Close confines at low speed, in particular, are no problem for the Superfly's nimble personality and we never felt like we were fighting the front end, even on tight uphill switchbacks.

High-speed handling is reassuringly stable for a dedicated cross-country bike, too, thanks to a smart 69.3-degree head tube angle that retains quick steering without feeling unnervingly twitchy and a low bottom bracket that keeps your center of gravity close to the ground. Coupled with the big wheels, there was generally little drama when mindlessly bombing through rock gardens but that same low bottom bracket will produce more than a few pedal strikes if you're not mindful.

Given the bike's racing intentions, it's no surprise that it's dutifully quick under power. Stiff carbon fibers and monstrous tube cross-sections – including Trek's ultra-wide 95mm bottom bracket shell and broadly spaced chainstays – yield a stout backbone and firm foundation for big pedaling efforts. Likewise, very good front triangle torsional rigidity keeps the bars from moving excessively when you're sprinting or climbing out of the saddle.

Add in the bike's impressive 9.66kg (21.30lb, complete, w/o pedals) weight and it's no surprise that the Superfly Pro is a perfect companion for long climbs. Riding position is similarly race-ready with a puny 103mm-long head tube on our 17.5in tester that produced a suitably low hand position when paired with a slightly negative-rise stem and flat bar.

Though stiff, the Superfly Pro isn't quite as unyieldingly efficient as some other machines we've tested recently. Likewise, ride comfort falls a bit shy of the best examples in the market with a rear end that filters out high-frequency buzz but doesn't offer much vertical flex to speak of. Trek attempt to ameliorate this with the Superfly Pro's slim 27.2mm-diameter seatpost but even that effort is thwarted by the Bontrager Race X Lite ACC post's aluminum core.

Despite this, overall comfort has improved over last year's Superfly Elite. The new Bontrager 29-1 tires are generously sized at 2.2in across and suitably floaty for all-around trail duty yet still roll extremely quickly thanks to the ramped, low center knobs. Add in the 15mm through-axle fork dropouts and the noticeable bump in front-end stiffness relative to last year's open dropouts, and the Superfly Pro is not only slightly more comfortable and a bit faster than before but also a more suitable all-around trail machine, too.

Frame: Huge cross-sections, wide spacing

In typical fashion, Trek infuse the Superfly Pro with lots of smart engineering but don't stray too far from convention in terms of tube shaping. Key features include a tapered 1-1/8 to 1-1/2in head tube and a 95mm-wide bottom bracket shell – both with molded-in carbon fiber bearing seats. There's also a highly asymmetrical seat tube, carbon dropouts with bolt-in aluminum plates and standard 135mm spacing, and especially wide-set chainstays that lend lots of tire clearance

A neat touch is the bonded-on rubberized plate on the down tube underside to ward off impacts from trail debris – something we made liberal use of on Colorado's notoriously rocky terrain. Frame weight is impressive, though not groundbreaking, at 1,340g including the rear derailleur hanger, seatpost collar, water bottle bolts, and chain stay and down tube guards (which aren't easily removable). Cables are externally routed beneath the top tube for easy maintenance and the front derailleur bolts directly to the seat tube to minimize positioning errors.

Equipment: Race ready but still trail friendly

As Trek's flagship cross-country race machine, little expense has been spared dressing up the Superfly Pro frame. Shift performance from the ultralight SRAM XX group was once again fantastic with uncannily positive and fast front shifts – even under climbing or at low cadence – coupled with impeccably precise and consistent rear shifts. In short, gear changes were simply something we never gave a second thought about during testing.

Likewise, the RockShox SID XX 29 fork was well suited for the task with an impressively sturdy chassis, smooth and smartly progressive action through the 100mm stroke, and a well-tuned damper that tackles both trail buzz and bigger hits with equal aplomb. More demanding and complicated sections of trail are still better handled by RockShox's more sophisticated Motion Control BlackBox damper but given the bike's cross-country focus, we're guessing most users will be willing to sacrifice a bit of ride control for the convenient XLoc hydraulic remote lockout lever.

We unfortunately can't heap the same level of praise on the Avid XX brakes. Lever feel, power, modulation and ergonomics were all excellent but both ends squawked loudly under hard braking – wet or dry, and regardless of pad or rotor condition. Both brakes were reliable throughout testing, but only after we bled the front straight out of the box.

The vast majority of the included Bontrager kit is excellent, in particular the Race X Lite Carbon Big Sweep flat bar with its comfy 12-degree bend, the comfortable and maneuverable Evoke 4 titanium railed saddle, and the fantastic 29-1 tires with their supple, high-volume casings, fast roll and surprisingly confident grip in all but marbles and mud.

As we noted last year, though, we'd still prefer to see a different seatpost included as the carbon-wrapped aluminum Race X Lite ACC model is too stiff to take advantage of its small 27.2mm diameter. We traded it out for Bontrager's softer – and lighter – Race XXX Lite all-carbon model and instantly got a big boost in ride comfort.

The included Bontrager Race X Lite FCC wheels are conveniently tubeless-ready (as are the tires, though the requisite rim strips and valve cores annoyingly aren't included with the bike) and they feel both stiff and sturdy enough for genuine trail use, not just race duty. Thankfully, we never experienced any of the unnerving pinging and popping from the freehub body that we encountered with last year's Bontrager hubs. However, they're a little heavy for a bike of this level, particularly given the premium US$6,829.99/£5,000 asking price.

One place we're happy not to see the Bontrager label, however, is on the grips. Last year's foam grips were light but too narrow, prone to rotating on the bar and uncomfortable. Trek have wisely switched to ESI's silicone foam rubber grips, which are still super-light but far more shock absorbent, grippier in your hands and far less apt to move. Perhaps the best testament is the fact that even Trek's own Subaru-Trek professional team have used these for years.

Overall, the Trek Superfly Pro is a top-shelf ride and undoubtedly a better bike than the Elite model we tested last year – but then again, it should be considering it's roughly US$2,000 more expensive. It won't be a world beater, however, until it gets nicer wheels, a softer seatpost and a more refined ride quality.

For example, a vendor or publisher might need to store a cookie on your device during your first visit on a website, to be able to recognise your device during your next visits (by accessing this cookie each time).
• A car manufacturer wants to promote its electric vehicles to environmentally conscious users living in the city after office hours. The advertising is presented on a page with related content (such as an article on climate change actions) after 6:30 p.m. to users whose non-precise location suggests that they are in an urban zone.
• A large producer of watercolour paints wants to carry out an online advertising campaign for its latest watercolour range, diversifying its audience to reach as many amateur and professional artists as possible and avoiding showing the ad next to mismatched content (for instance, articles about how to paint your house). The number of times that the ad has been presented to you is detected and limited, to avoid presenting it too often.
• If you read several articles about the best bike accessories to buy, this information could be used to create a profile about your interest in bike accessories. Such a profile may be used or improved later on, on the same or a different website or app to present you with advertising for a particular bike accessory brand. If you also look at a configurator for a vehicle on a luxury car manufacturer website, this information could be combined with your interest in bikes to refine your profile and make an assumption that you are interested in luxury cycling gear.
• An apparel company wishes to promote its new line of high-end baby clothes. It gets in touch with an agency that has a network of clients with high income customers (such as high-end supermarkets) and asks the agency to create profiles of young parents or couples who can be assumed to be wealthy and to have a new child, so that these can later be used to present advertising within partner apps based on those profiles.
• An online retailer wants to advertise a limited sale on running shoes. It wants to target advertising to users who previously looked at running shoes on its mobile app. Tracking technologies might be used to recognise that you have previously used the mobile app to consult running shoes, in order to present you with the corresponding advertisement on the app.
• A profile created for personalised advertising in relation to a person having searched for bike accessories on a website can be used to present the relevant advertisement for bike accessories on a mobile app of another organisation.
• You read several articles on how to build a treehouse on a social media platform. This information might be added to a profile to mark your interest in content related to outdoors as well as do-it-yourself guides (with the objective of allowing the personalisation of content, so that for example you are presented with more blog posts and articles on treehouses and wood cabins in the future).
• You have viewed three videos on space exploration across different TV apps. An unrelated news platform with which you have had no contact builds a profile based on that viewing behaviour, marking space exploration as a topic of possible interest for other videos.
• You read articles on vegetarian food on a social media platform and then use the cooking app of an unrelated company. The profile built about you on the social media platform will be used to present you vegetarian recipes on the welcome screen of the cooking app.
• You have viewed three videos about rowing across different websites. An unrelated video sharing platform will recommend five other videos on rowing that may be of interest to you when you use your TV app, based on a profile built about you when you visited those different websites to watch online videos.
• You have clicked on an advertisement about a “black Friday” discount by an online shop on the website of a publisher and purchased a product. Your click will be linked to this purchase. Your interaction and that of other users will be measured to know how many clicks on the ad led to a purchase.
• You are one of very few to have clicked on an advertisement about an “international appreciation day” discount by an online gift shop within the app of a publisher. The publisher wants to have reports to understand how often a specific ad placement within the app, and notably the “international appreciation day” ad, has been viewed or clicked by you and other users, in order to help the publisher and its partners (such as agencies) optimise ad placements.
• You have read a blog post about hiking on a mobile app of a publisher and followed a link to a recommended and related post. Your interactions will be recorded as showing that the initial hiking post was useful to you and that it was successful in interesting you in the related post. This will be measured to know whether to produce more posts on hiking in the future and where to place them on the home screen of the mobile app.
• You were presented a video on fashion trends, but you and several other users stopped watching after 30 seconds. This information is then used to evaluate the right length of future videos on fashion trends.
• The owner of an online bookstore wants commercial reporting showing the proportion of visitors who consulted and left its site without buying, or consulted and bought the last celebrity autobiography of the month, as well as the average age and the male/female distribution of each category. Data relating to your navigation on its site and to your personal characteristics is then used and combined with other such data to produce these statistics.
• An advertiser wants to better understand the type of audience interacting with its adverts. It calls upon a research institute to compare the characteristics of users who interacted with the ad with typical attributes of users of similar platforms, across different devices. This comparison reveals to the advertiser that its ad audience is mainly accessing the adverts through mobile devices and is likely in the 45-60 age range.
• A technology platform working with a social media provider notices a growth in mobile app users, and sees based on their profiles that many of them are connecting through mobile connections. It uses a new technology to deliver ads that are formatted for mobile devices and that are low-bandwidth, to improve their performance.
• An advertiser is looking for a way to display ads on a new type of consumer device. It collects information regarding the way users interact with this new kind of device to determine whether it can build a new mechanism for displaying advertising on this type of device.
• A travel magazine has published an article on its website about the new online courses proposed by a language school, to improve travelling experiences abroad. The school’s blog posts are inserted directly at the bottom of the page, and selected on the basis of your non-precise location (for instance, blog posts explaining the course curriculum for different languages than the language of the country you are situated in).
• A sports news mobile app has started a new section of articles covering the most recent football games. Each article includes videos hosted by a separate streaming platform showcasing the highlights of each match. If you fast-forward a video, this information may be used to select a shorter video to play next.
• An advertising intermediary delivers ads from various advertisers to its network of partnering websites. It notices a large increase in clicks on ads relating to one advertiser, and uses data regarding the source of the clicks to determine that 80% of the clicks come from bots rather than humans.
• Clicking on a link in an article might normally send you to another page or part of the article. To achieve this, 1°) your browser sends a request to a server linked to the website, 2°) the server answers back (“here is the article you asked for”), using technical information automatically included in the request sent by your device, to properly display the information / images that are part of the article you asked for. Technically, such exchange of information is necessary to deliver the content that appears on your screen.

Quick Review: Trek Superfly 100 29er Full Suspension MTB

While at the SE Bike Expo this past weekend, I got a chance to throw a leg over the new 2012 Trek Superfly 100.

As many of you already know, the Trek Superfly 100 is a carry over from the Gary Fisher days. Trek brought the two brands together to essentially give them a Trek branded 29er lineup. They kept the Gary Fisher name by making it a collection , but you are basically getting the same bike as before with the Trek logo. Trek owned Gary Fisher anyway, so it really made sense from a branding point of view.

For 2012, the big change to the bike was the addition of the 142mm rear end with 12mm rear thru axle. This does a lot to stiffen up the rear end and unify the rear triangle with the front main frame. We are starting to see a lot of manufacturers go to this setup over the past couple of years. While it creates yet another variable (the 142mm rear hub width vs. conventional 135mm), anything that brings more rear end stiffness to full suspension mountain bikes is a welcomed bonus.

The bike still features the Trek Active Braking Pivot a RockShox Maxle thru axle system.

The color scheme also changed for 2012 to a raw carbon look (vs. the white previously) with bright blue accents. Personally, I am liking the darker color scheme Trek is using for their lineup this year. The Fuel EX and Remedy got the same treatment. Other than that, you get the same G2 geometry that you are used to out of the 29ers from Fisher and a host of Bontrager/Shimano components to round out the build. Weights for this Elite model (MSRP $5,249) are coming in around 26 pounds.

One thing to keep in mind with current Trek bikes, their sizing is a little bit different than you might be used to. I typically ride a large in just about all brands. On a 2012 Trek, I ride a 21.5 frame because it is an actual 19.5. When you go to test ride a Trek, try the one size up than you normally ride first.

The Trek Superfly 100 is a purpose built machine in all reality. While there will be a lot of enthusiast riders who buy this bike purely because they want a light 29er, the real purpose of this bike is to go fast on XC race courses and endurance events. During these events, all of your time that is made up to hit the podium is done on climbs…not the descents. So fast race machines have to be able to climb like a bat out of hell. They don’t really care how they descend…just get me to the top and do it quickly.

The Superfly 100 is built to do exactly that…climb. When you get into slight rises or long ascents, the bike seems to just pedal forward with enough suspension to gain traction without robbing you of precious energy. The Active Braking Pivot does a great job of preventing unwanted pedal bob while hammering up the climb and the geometry of the bike keeps the front end planted down while tracking straight. Basically, everything you would want the bike to do while climbing…just works.

That is where the love affair with the Superfly 100 stops…at least for me. Those same stable characteristics that make the Superfly 100 such a great climber are it’s downfall in tight/twisty singletrack and downhill. The suspension on the Superfly (at 25% sag) is really setup just to take enough of the edge off that you don’t get super beat up on XC races. You still feel just about every single part of the trail while you ride. It is not a plush setup even when you start to let air out of the 110mm rear travel frame.

That stability you feel in the climbing is also largely in part because of a long wheelbase on this bike. That same long wheel base makes the bike hard to maneuver between tight trees and switchbacks. It is more of a sweeping turner than a pinpoint direction changer. It takes more body english and throwing your weight forward on the bike to get it to spin around.

While headed downhill, the Active Braking Pivot works as advertised by keeping the suspension active under braking forces, but the bike just isn’t comfortable with the tires leaving the ground or bombing technical descents. However, I would expect this out of a bike that is essentially built to be a mountain goat.

Overall, the bike is great for what it is built to be…a light XC race/endurance bike that will make up time where it matters the most…on the climbs and flats. It pedals incredibly well and makes you feel like you are faster than you are when you are pointed skyward. Throw a little bit of money at this Elite (ok…maybe a lot of money) and you could have a 23 lbs. racing monster that will get you to the podium.

Those same characteristics that make this bike such a great racing thoroughbred make it a hard sell for enthusiast riders in my eyes. If you want to have the latest and greatest light full suspension mountain bike frame, then you are probably looking right at this offering from Trek. However, I think there is more fun to be had on several other bikes in the industry (especially for this price) if you are looking to maximize your fun on the trail and not just be the first one to the top of the climb. It is not going to be confidence inspiring going downhill unless you already have some serious skills.

For my purposes, I would look into this frame if I was going to race endurance events. For fast XC racing, I would probably look closer at the Niner Jet 9 RDO as it’s geometry will turn faster through tight sections of trail.
