Trek Marlin 7 Womens Mountain Bike 2021

With the frame design, wheels and finishing kit size-specific, the Trek Marlin 7 Women's Mountain Bike is optimised for every rider, creating a more dialled-in feel and improved handling across the board. This is a hardtail that's ideal for cyclists looking to develop skills and maybe try their hand as cross country racing, pairing a light aluminium frame with a RockShox Judy fork that offers 100mm of travel and can be locked out when you hit smoother terrains. Mounts for a rack and kickstand make this bike even more versatile.

Built-up with Shimano 1x10-speed Deore components, you get both reliability and performance in the shifting and hydraulic braking. An 11-42 cassette provides a wide range of gears and with only a single chainring, operation and maintenance are simplified. All cables are routed internally, keeping them away from the elements that can reduce lifespan. Rolling on Bontrager wheels and tyres in either a 27.5" or 29" size, rolling is fast and smooth, and you get excellent traction across a variety of terrains.


  • Lightweight Alpha Silver Aluminium frame
  • RockShox Judy fork with 100mm travel and lockout feature
  • 1x Shimano Deore 10-speed drivetrain, wide-ranging 11-46-tooth cassette and hydraulic disc brakes
  • Internal cable routing
  • Marlin models in XS and S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount
