Trek Marlin 8 Gen 3
The 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 mounts for racks and a kick stand. It's built for years of progress thanks to 12-speed SRAM shifting and an upgraded RockShox air-spring suspension fork.
It's right for you if...
You want a bike that's ready to progress with you on the trail, and is versatile enough for daily riding to school, work and grocery shopping.
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. An air-spring RockShox fork that's lighter and more adjustable than a coil spring, wide-range SRAM shifting and the serious stopping power of hydraulic disc brakes.
The final word
The Marlin 8 is a progressive trail bike ready for building skills on the singletrack, and taking on daily life too. It packs in premium features where you want them so you can build skills for years to come.
