It’s right for you if…

You’re new to the trail but have serious singletrack aspirations, and want a versatile, race-worthy mountain bike with upgrades on the parts that make a big difference in performance, like a higher-quality suspension fork and a simple 1x drivetrain.

The tech you get

A light frame with internal shift cable and brake hose cable routing, a smoother-feeling RockShox Judy fork with a lockout, Shimano hydraulic disc brakes and Bontrager wheels. A simple 1x drivetrain ditches the front derailleur for less clutter and easier operation. Don’t worry, with the wide-range 11-46 cassette, you still get all the gears you need for clawing up climbs and blazing down descents.

The final word

The RockShox suspension, wide range of gearing, and quality parts make it the best choice in the Marlin line-up for new mountain bikers who know they want a serious bike for their money. It’s fully capable of taking on big trail adventures and XC races.
