Details

Marlin 8 is a confidence-boosting trail bike with updated geometry that gives you more control on singletrack without skipping on features for everyday use like daily riding to school, work, and grocery shopping.

It's built for years of progress thanks to the premium wide range 1x12-speed SRAM SX Eagle drivetrain, serious stopping power of hydraulic disc brakes and an upgraded RockShox air spring suspension fork.

The air-spring RockShox fork is lighter and more adjustable than a coil spring.

The Marlin 8 Gen 3 also features a lightweight aluminum frame with modern trail riding geometry and internal routing that keeps cables protected and keep the bike looking sleek.

Integrated rack and kickstand mounts make it easy to add accessories to this versatile steed.

What you get over Marlin 7 Gen 3:

- 1x12-speed SRAM SX Eagle drivetrain
- RockShox air spring suspension fork

Wheel size:
- Size XX-Small: 26-inch
- Sizes X-Small – Small: 27.5-inch
- Sizes Medium – XX-Large: 29-inch

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

Full-length, full-coverage guards on the chainstay protect your frame and keep your ride quiet.

Rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter.

A new Thru-Skew axle provides better rear wheel security, holding your wheel in place snugly and ensuring it doesn't slip out of the frame, even when you're rolling through rough-and-tumble terrain.
