Trek Marlin 6 Womens Mountain Bike 2021
The Trek Marlin 6 Womens Mountain Bike is not only very capable off-road it also works well as a solid commuter with integrated mounts for a rack and kickstand. With reliable components, 100mm of bump-smoothing suspension in the SR Suntour XCT 30 fork and women's, frame-size-specific finishing kit, this bike will help you build skills and confidence out on the trails.
There are plenty of gears on the Shimano Altus 2x8-speed drivetrain to assist you on the hills yet not hold you back when you want to pick up speed, and hydraulic discs are reliable in their power, in both the wet and dry. The design of the frame itself, the wheels sizes, brake levers and handlebar width are all frame-size-specific. This means a more dialled-in, comfortable and efficient position and ride for every rider.
- Lightweight Alpha Silver Aluminium frame
- RockShox Judy fork with 100mm travel and lockout feature
- Shimano Altus 2x8-speed drivetrain, wide-ranging 11-34-tooth cassette and hydraulic disc brakes
