Mountain bikes can exist.

It's the right bike for you if...

...you're looking for a race-ready mountain bike that boasts parts upgrades that make the biggest difference in performance, like a lighter, higher-quality suspension fork, a wide-range 1x drivetrain, and tubeless ready wheels.

You get this equipment

A lightweight frame with internal cable routing, a smooth RockShox Judy Silver suspension fork with Solo Air spring and hydraulic TurnKey lockout, Shimano hydraulic disc brakes, Bontrager Kovee Tubeless Ready wheels and a straightforward 1x12 drivetrain that eliminates the need for a front derailleur thus contributing to a tidy look and easier operation. Thanks to the 11-50 cassette with a wide gear range, you have all the gears you need to climb the steepest climbs and blast down fast descents.

Why you'll love it

1. This is one of our most popular bikes - and for good reason. An unbeatable price for extra versatility in a mountain bike that is fully suitable for racing and can also be equipped for the daily commute thanks to the rear luggage rack eyelets
2. The RockShox suspension fork's Solo Air spring is lighter than a steel spring and can be easily adjusted to a specific rider weight
3. A tubeless setup reduces the overall weight of your bike and the risk of a flat tire
4. With the 1x drive you have all the gears you need
5. Marlin models in frame sizes XXS to S come with a curved top tube and a lower standover height to make it easier for smaller riders to get on and off
