Trek Fuel EX 8 XT Gen 6 Mountain Bike
Dialled for rowdy descents, pedalling up the other side and everything in between, the Trek Fuel EX 8 XT Gen 6 Mountain Bike suits riders looking for full-suspension, versatile performance. The alloy frame is light and stiff with 140mm travel and a Fox Factory Float X shock. It's paired with a Fox Rhythm 36 fork with frame size-specific travel, ensuring a plush, bump-smoothing ride.
Progressive geometry is able to handle the rough stuff, providing stability and pedalling efficiency, and a Mino Link and adjustable angle headset (angled cups sold separately) allow customisation to suit both rider and ride.
A Shimano XT drivetrain delivers snappy, precise shifting and offers a wide gear range. The hydraulic discs keep braking reliably powerful in all conditions. TranzX's JD-YSP39 dropper post means it's easy to drop the saddle down and out of the way in an instant for optimal body positioning.
Wheel size is frame-size dependent, and the bike rolls on either 27.5" or 29" wheels fitted with Bontrager XR5 Team Issue tubeless-ready tyres for traction, fast rolling and puncture protection.
