2024 Trek Marlin Gen 3

With 8 different sizes, the 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.

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.

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 135 mm rear hub spacing.
