Trek Roscoe 8 Womens Mountain Bike 2020

Trek's Roscoe 8 Womens Mountain Bike is a serious off-road machine with performance and ability which belies its very reasonable price point. The hardtail Alpha Gold Aluminium frame is both lightweight and efficient, with internal cable routing for aesthetics and protection against dirt. There is a 120mm air-sprung suspension fork from RockShox (100mm size XS) to help keep the front wheel gripping the ground and to provide cushioning against bumps, as well as a dropper seatpost that allows the saddle to be instantly lowered for increased confidence and manoeuvrability when the trail gets really steep or technical.

The 27.5” wheels have wide Maxxis Rekon 2.8” tyres for even more grip and comfort whilst the Shimano MT500 hydraulic disc brakes provide great stopping power with just a light pull of the lever so that the speed comes with control. SRAM’s 12-speed NX Eagle drivetrain has a single ring at the front and a super-wide range cassette so that there is always an appropriate ratio easily to hand without the complication of a front derailleur.
