Trek Fuel EX 9.7 NX/GX Mountain Bike 2021
Trek’s Fuel EX 9.7 NX/GX Mountain Bike is designed to take on any trail, be it uphill, downhill or twisty singletrack in between. The 130mm travel OCLV Mountain Carbon frame uses a FOX Performance Float EVOL rear shock with RE:aktiv 3-position damper for excellent grip and controlled plushness whilst the front end has 140mm of travel from its FOX Rhythm 36 Float EVOL fork. By switching the Mino Link in the shock linkage around, the geometry can be slackened off and the bottom bracket lowered for greater stability, and the Knock Block and Carbon Armor protect the bike against damage from rocks or crashes.
SRAM’s 12-speed drivetrain comprises NX and GX components, with the wide-range 11-50 tooth cassette providing plenty of ratios for all eventualities. 4-piston Shimano MT420 hydraulic disc brakes ensure tireless stopping power and easy modulation, with the Bontrager Line Dropper seatpost adding further convenience and control. Both the Bontrager Line Comp 30 wheelset and the XR4 Team Issue tyres are tubeless-ready and by offering both 27.5” and 29” options depending on frame size, handling is kept consistent across the range.
