Trek Marlin 7 Gen 2 Review: Affordable, Feature-Rich XC MTB

The Trek Marlin 7 Gen 2 is the second-from-top model in this family of versatile cross-country hardtails. 

The Marlin 7 is ideal for beginner mountain bikers who want to experience light off-road riding and use their bike for mixed-terrain commuting, bikepacking, and running errands.

However, although it looks the part, entry-level components mean this bike is limited in its capability on the trail.

The 2023 model is the same as the Trek Marlin 7 2022, only with an updated ‘Gen 2’ label, a feature of the brand’s new naming system for the upcoming year.

This Trek Marlin 7 review aims to help you figure out if it’s the right bike for you and your needs. 

How Much is the Trek Marlin 7?

Trek Marlin 7’s price is $1,030. The cheaper Marlin model costs $850, so for just $180 more, this bike has an improved RockShox fork, Shimano hydraulic disc brakes, and a bottom bracket and crankset from FSA. While these upgrades are modest, they easily justify the extra money. 

• RockShox fork
• Shimano hydraulic disc brakes
• Progressive sizing
• No tubeless-ready rims or tires

Trek Marlin 7 2023 Full List of Specs

Trek marlin 7 gen 2 full review, what kind of bike is a trek marlin 7.

So is the Trek Marlin 7 a trail bike? Not quite. Trail MTBs have 130mm or more of suspension travel; this model is a cross-country hardtail mountain bike for beginners.

Marlin 7 is available in three diverse color schemes, which makes it attractive to a wide range of riders.

The Marlin 7 has entry-level components to match the affordable price and thus has limitations on its ability to handle rougher trails. However, it performs well as a day-to-day bike for recreation, transport, and commuting. 

RockShox Judy Coil Fork 

RockShox’s Judy Silver coil spring fork is a notable inclusion at the ~$1,000 price point. This fork is light for the price and provides decent ride characteristics for a coil spring. In general, mountain bikes in this price range will have SR Suntour forks, like the cheaper Marlin models. 

The RockShox Judy coil fork offers 100mm of travel, but is not suitable for heavy-duty trial riding. However, it can handle dirt and gravel roads with ease.

The 100mm travel (80mm on XS) Judy Silver coil fork uses TurnKey lockout , which absorbs an unexpected hit with the lockout on, so you don’t blow it out. It also has preload adjustment.

Full Shimano Groupset

The Trek Marlin 7 is the only one of the five bikes to have a complete Shimano groupset , consisting of a Deore 10-speed drivetrain and MT200 hydraulic disc brakes, a solid, reliable setup for this price. 

Shimano’s Deore 10-speed groupset is a good fit for this bike as its parts are affordable to replace (such as the chain and cassette), yet it provides plenty of range and crisp shifting.

This drivetrain mixes a Deore 11-46t cassette with an FSA Alpha Drive 28t crankset, providing plenty of range for steep climbs. In addition, the Shimano shifters and derailleur can take a beating and maintain a relatively smooth shifting performance. 

Shimano hydraulic disc brakes are another noteworthy inclusion in this price range, as most brands use Tektro to keep costs down. These brakes are plenty powerful and dependable for a light-use mountain bike like the Trek Marlin 7.

Progressive Frame and Wheel Sizing

A shared design feature across the Trek Marlin family is the progressive sizing that provides a consistent fit across the wide range of rider heights.

The Marlin 7 has seven sizes spanning 4’9″ to 6’8″. For this reason, modifying the geometry and components was essential so the shortest rider gets the same experience as the tallest . To achieve this, Trek uses a curved top tube on the smaller sizes for a lower standover height, ‘Smart Wheel Sizes’ for a wheel that fits (27.5 or 29″), and short-reach brake levers and narrower handlebars for better control.

Trek Marlin 7 Gen 2 Sizing Chart

• XS — 4’9″-5’1″ / 145-155cm
• S —  5’1″-5’5″ / 155-165cm
• M —  5’5″-5’8″ / 165-173cm
• M/L — 5’8″-5’11” / 173-180cm
• L —  5’11”-6’2″ / 180-188cm
• XL —  6’2″-6’5″ / 188-195cm
• 2XL — 6’5″-6’8″ / 195-203cm

Who Is Trek Marlin 7 Gen 2 Best Suited For?

Trek’s Marlin 7 XC mountain bike is ideal for beginners who want a first bike to experience the trail and handle daily riding, such as commuting to work or school, transport around the city, or even multi-day bikepacking trips . 

With a rear rack fitted, Trek Marlin 7 transforms into a capable daily commuter or bikepacking companion.

The affordable price tag makes this model accessible to a wide range of budgets. In addition, the reliable Trek aluminum frame means you upgrade components as you develop your mountain biking skills. Unfortunately, the fork limits you to light off-road riding, so consider the Trek Marlin 8 if you want a more capable hardtail.

Is Marlin 7 Gen 2 a Good Buy?

This Trek bike is another competitive choice in the $1,000 price range . Innovative frame engineering, a solid Bontrager build kit, and reliable Shimano componentry make this bike a good deal. 

Marlin 7 in navy blue looks serious in elegant, which is just one of the three modern-looking paint jobs available.

Trek Marlin 7 reviews we’ve read online are overwhelmingly positive, emphasizing the value for money that it offers. Sure, it’s not very capable on bumpy terrain, but it serves its purpose as a beginner’s hardtail, giving you the opportunity to develop your technique on a bike that can do a bit of everything, on and off-road. 

Add the Marlin 7 to your shortlist if you want a stylish and affordable cross-country hardtail that’s built to last.

Trek Marlin 4 Gen 2

Marlin 4 is the perfect gateway to trail riding. It's ideal for new riders who want a mountain bike with knobby tires that can double as a rugged commuter. Disc brakes, front suspension, 21 speeds, and mounts for a rack and fenders make this a great bike for new trail riders and campus commuters alike. It's right for you if... You want an introductory mountain bike at an incredible price but also want a commuter that's rugged enough to hop curbs on the way to class. The tech you get A lightweight aluminum frame with internal routing to protect your cables and add to the bike's sleek look, 21 speeds, a wide range of gearing so you always have the right gear for your terrain, powerful mechanical disc brakes, and a suspension fork that takes the edge off bumps and rough terrain. The final word Marlin is made for any adventure. The rack and fender mounts make it a great choice for commuters who want to get a little rad on the way to class or the grocery store. Why you'll love it - It's a real mountain bike that's also perfectly suited to daily commutes, rides around campus, or just getting from A to B on any surface - Rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter - Smaller frame sizes (XS and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently - Marlin models in XS and S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount - Like every model in the Marlin family, it's backed by Trek's lifetime warranty Wheel size: - Sizes X-Small – Small: 27.5-inch - Sizes Medium – XX-Large: 29-inch

Will my bike have a curved top tube?

Smaller frames (XXS-S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Due to supply-chain issues, Specs are subject to change without notice.

5 things to do before every mountain bike ride

Do this quick pre-ride safety check before you hit the trails.

Product features

Will my bike have a curved top tube.

Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Fit for every rider

Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value

Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.

Rear kickstand mount

Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.

Rack mounts

Going for a long ride? Rack mounts make carrying accessories a breeze.

Blendr stem

Bontrager stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

Internal cable routing

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.

Mechanical disc brakes

Reliable stopping power in all conditions, including wet and muddy.
