Trek Fuel EX 9.8 GX Eagle 29" Mountain Bike 2020
The Trek Fuel EX 9.8 GX Eagle 29" Mountain Bike makes a great trail bike for riders who like to do a bit of everything, with a high-quality frame, fork and components that are highly capable and hugely versatile.
The carbon frame has 130mm of travel using a FOX Performance FLOAT EVOL rear shock with RE:aktiv Thru Shaft 3-position damper for improved ground tracking. It also features Trek’s Mino Link in the rocker that allows the geometry to be switched between two positions, making it slacker or steeper. The integrated BITS storage and internal cable routing keep things neat and tidy whilst the Knock Block design protects the frame from the fork crown.
The 29” Line Carbon 30 wheels and XR4 Team Issue tyres from Bontrager are both tubeless-ready for increased puncture resistance and the potential for lower pressures, whilst the Bontrager Line Elite Dropper seatpost gets the saddle out of the way quickly for greater confidence and manoeuvrability on steep ground.
SRAM’s 12-speed GX Eagle drivetrain and Shimano’s SLX 4-piston hydraulic disc brakes both perform their duties with minimum fuss and maximum effectiveness, meaning that all the rider has to concentrate on is having fun.
