Trek Fuel EX 7 NX Mountain Bike 2021
Trail-ready with dependable components and a full suspension chassis, Trek’s Fuel EX 7 NX Mountain Bike makes a great all-round off-road option. The Alpha Platinum Aluminium frame has 130mm of suspension and the RockShox 35 Gold fork has 140mm, which helps to keep the traction levels high when climbing and tames the bumps on the way back down. There is a choice between two geometry settings, one with greater stability and the other with sharper handling, which can be switched between using the Mino Link.
Shimano MT400 hydraulic disc brakes and SRAM’s 12-speed NX drivetrain offer powerful braking and crisp shifts, with the wide-range cassette providing plenty of ratios for hills and descents alike. When the riding becomes steep or technical, the TranzX JD-YSP18 dropper seatpost allows the saddle to be lowered out of the way increasing both confidence and manoeuvrability. Bontrager supply the wheels and rubber in the form of their tubeless-ready XR4 Team Issue tyres and Line Comp 30 wheelset, so taking advantage of the ability to run lower pressures without pinch puncture concerns is a simple task.
