It's right for you if...
You're new to the trail but have serious single-track aspirations, 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.
The tech you get
The flagship model of the Marlin line-up has a lightweight Alpha Silver Aluminium frame with internal shift cable and brake hose routing to protect your cables and add to the bike's sleek look, a high-quality RockShox fork with a lockout feature and 100 mm of travel, a 2x9 drive train, Shimano hydraulic disc brakes and a low-profile Shimano Shadow rear derailleur that's designed to avoid snagging on trail debris.
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 off-road marathon rides and XC races.

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.
Going for a long ride? Rack mounts make carrying accessories a breeze.
Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.

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.
