Trek Project One Fuel EX 9.8 GX Eagle 27.5" Mountain Bike 2020
The Trek Project One Fuel EX 9.8 GX Eagle 27.5" Mountain Bike is based around a full-suspension carbon frame with 130mm of travel from a FOX Performance FLOAT EVOL rear shock that has RE:aktiv with Thru Shaft 3-position damper for better ground tracking. The frame also has Knock Block to prevent the fork crown from hitting the frame, BITS internal storage for tools, and Trek’s Mino Link that switches the geometry between two options by simply flipping a chip in the rocker depending on rider preference or usage. The frame is paired with a 140mm FOX Performance 36 FLOAT EVOL air spring fork with GRIP damper for added plushness and tunability
By using 27.5” Bontrager Line Carbon 30 wheels rather than 29” with the smaller frame, the nimble handling and ride quality is maintained, and both the wheelset and the XR4 Team Issue tyres are tubeless-ready for easy conversion. Bontrager also supplies the dropper seatpost which allows the saddle to be dropped and raised on the fly for tricky sections. Shimano SLX hydraulic disc brakes are specced alongside SRAM’s 12-speed GX Eagle drivetrain, ensuring performance and reliability.
