Trek marlin 8 gen 3

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. Its built for years of progress thanks to 12-speed SRAM shifting, and an upgraded RockShox air spring suspension fork.

• You get real-deal modern mountain bike geometry that keeps handling confident when youre on singletrack, but its versatile enough for use on roads and bike paths, too
• You get a premium RockShox fork with an air spring thats 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

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 Marlins popularity is a real trail-savvy mountain bike frame thats 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.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
