Description
SRAM 12-speed components, a tough aluminium frame and FOX shock unit help make the Trek Fuel EX 8 GX Mountain Bike perfect for trail riding of any kind. With 140mm of travel from the Rhythm 34 fork and 130mm from the Performance Float EVOL rear shock, traction is superb whilst larger hits are equally well dealt with and by flipping the Mino Link over the angles can be slackened for greater stability at speed.
The 10-52 tooth 12-speed cassette has the largest range available, ensuring that the right ratio is always at hand and the 4-piston G2 R hydraulic disc brakes give great control when the time comes to head downhill. Confidence is also boosted by the inclusion of the Bontrager Line Dropper seatpost which allows the saddle to be quickly dropped out of the way for greater manoeuvrability when required.
Wide Bontrager Line Comp 30 wheels provide good support for the XR4 Team Issue tyres, and by using 27.5” wheels on the smaller sized bikes and 29” on the larger sizes handling has been kept consistent for all riders. As both wheelset and tyres are tubeless-ready, the conversion is simple, allowing for lower pressures and improved grip without the risk of pinch punctures.
