Trek Fuel EX 9.8 GX
The Trek Fuel EX 9.8 GX features an elegant carbon frame and makes a very high-quality impression with its semi-translucent red finish with visible carbon fibres. It has 140 mm travel at the front and 130 mm at the rear and comes equipped with a Thru Shaft technology shock, developed specially by RockShox for Trek. The shock uses fewer seals, which is claimed to reduce friction and improve sensitivity. Trek’s proprietary internal storage compartment in the down tube offers enough room to stow a spare inner tube, a CO2 cartridge and a few trail snacks. A long TPU down tube guard protects the carbon frame from impacts and stray rocks. The chainstay protector prevents chain slap and ensures a quiet ride, making the Trek one of the quietest bikes in the test. The integrated Knock Block limits the steering angle and thus prevents the fork crown from damaging the frame or cables from tearing off. You never hit that limit on the trail but it could pose some issues when transporting the bike.
