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 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 aluminum frame with modern trail riding geometry and internal routing that keeps cables protected and keep 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
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.

Why you'll love it
- You get real-deal modern mountain bike geometry that keeps handling confident when you're on singletrack, but it's versatile enough for use on roads and bike paths, too
- You get a premium RockShox fork with an air spring that's lighter and more adjustable than a coil
- You get the simplicity and range of 1x12 drivetrain for putting down power on the trail
- The included dropper post lets you get your saddle out of the way when you roll into technical sections and steeper descents.
- Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount

Features:

Expanded size range
With 8 different sizes, Marlin has a bike made to fit every rider. Each frame is equipped with smart wheel sizing, with XXS frames rolling on 26" wheels, and wheel sizes increasing proportionally along with frame sizes, so every rider gets the fit they need.

Trail-ready, Upgrade-ready
The secret to Marlin's popularity is a real trail-savvy mountain bike frame that's upgrade compatible, so it can grow with you as you take on bigger trails and tougher features.

Roll stronger with Thru Skew
Goodbye open dropouts. The Thru Skewer is a better, stronger, more precisely aligned rear wheel retention system that keeps your wheel more secure than quick-release skewers while still using the standard 135mm rear hub spacing.
