It's right for you if...
You're new to the trail, but you’re pretty darn sure you’ll fall in love with mountain biking, and want a race-worthy mountain bike with upgrades on the parts that make a big difference in performance, like a higher-quality suspension fork, wide-range 1x drive train and tubeless-ready wheels.
The tech you get
A light frame with internal cable routing, a smoother-feeling RockShox Judy Silver fork with a TurnKey hydraulic lockout, Shimano hydraulic disc brakes, tubeless-ready Bontrager Kovee wheels and a simple 1x drive train that ditches the front derailleur for less clutter and easier operation. The wide-range 11-50 cassette gives you all the gears you need for clawing up climbs and blazing down descents.
The final word
The tubeless-ready wheels, RockShox suspension, wide range of gearing and quality parts make it an outstanding choice for new mountain bikers who know they want a serious bike for their money. It’s fully capable of taking on off-road marathon rides and XC races.
The Walkthrough
favorite_borderWhy you'll love it
- This is one of our most popular bikes for good reason. You get all the value, plus all the versatility – it's a totally race-worthy mountain bike, with rear rack mounts if you use it for commuting too
- Setting your wheels up tubeless reduces the overall weight of your bike and the chances that you’ll get a flat
- It's really fun to ride, and feels like a much more expensive mountain bike
- The 1x drive train gives you all the gears you need and none you don’t
- The Marlin models in XXS to S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount
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.
Suspension lockout
Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
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 and 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.
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.
