Trek Marlin 6 Gen 3 27.5" MTB 2026

The Marlin 6 is the perfect ride for progressing your skills on the trails. Its updated slacker frame geometry makes it easier to control on descents while the suspension fork takes the edge off bumpy trails. Integrated rack and kickstand mounts make it easy to add accessories to this versatile steed.

High Tech High Value

Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Shimano CUES

Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings.

Better Aluminum

Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make – this one included – had made the switch, driving a major drop in our footprint.

Shimano LINKGLIDE

LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting – along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.
