Trek marlin 6 gen 3

• 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
• Fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter
• The new Thru-Skew system is safer, simpler, and stronger, plus it makes removing the rear wheel for flat fixes a cinch.
• Internal routing makes it easy to add a dropper post that lets you lower you saddle on the fly for more confident descending
• 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.
