Description

The Marlin 6 is the perfect ride for progressing your skills on the trails. Its updated slacker frame geometry makes it easier to control on descents while the upgraded suspension fork takes the edge off bumpy trails. Integrated rack and kickstand mounts make it easy to add accessories to this versatile steed.

It’s right for you if…

You want a trail bike that’s dialled for building confidence on the dirt, and versatile enough for commuting to work or school.

The tech you get

A lightweight aluminium frame with modern trail riding geometry and internal routing that keeps cables protected and keeps the bike looking sleek. A 100 mm RockShox Judy front suspension fork that cushions rocks, roots and bumps in the trail, 10-speed fuss-free Shimano CUES shifting and the serious stopping power of hydraulic disc brakes.

The final word

The Marlin 6 is an ideal trail bike for riders who want to progress on the dirt, and want a bike that can keep them rolling off of the trail, too.
