Overview
About this bike
Marlin 6 is a quality introductory cross country mountain bike with front suspension, 24 speeds, and a wide range of gearing for easier pedaling on climbs. It's built in Trek's trail heritage, but also equipped with features like rack and fender mounts that make it a great choice for daily commuters. It's right for you if... You're testing the waters of off-road riding, and want a real mountain bike at a great value, with a wide range of gears to cover more ground on the road and trail. The tech you get: Marlin 6 has 24 speeds, a wide-range cassette so you can always find the right gear for your terrain, hydraulic disc brakes that feel smoother than mechanical disc brakes, and a 100mm suspension fork with a lockout feature—that's the same amount of travel favored by most cross country racers. The final word: Marlin 6 is built to stand up to the trail, but also equipped with rack and fender mounts and a wider range of gears that make it a great choice if your mountain bike doubles as your commuter.
