Trek Fuel EX 8 GX Eagle 27.5" Mountain Bike 2020
Offering versatility, capability and value, Trek’s Fuel EX 8 GX Eagle 27.5" Mountain Bike makes a compelling argument for itself as a one-bike-only option. With a 130mm travel Alpha Platinum Aluminium frame and a 140mm FOX Rhythm 34 FLOAT EVOL air spring fork, it is able to pile on the smiles when descending and make the climbs enjoyable too. The GRIP damper in the rear shock unit does a good job of providing an efficient platform for pedalling yet still remaining compliant enough to absorb smaller bumps. The magnesium rocker features Trek’s Mino Link which offers two geometry settings, a steeper and a slacker option, so that the handling characteristics can be customised. The Active Braking Pivot (ABP) rear triangle design prevents the suspension from being effectively locked out under braking, so that it remains supple at all times whilst the Knock Block system stops the fork crown from spinning into the down tube.
Shimano hydraulic disc brakes and a SRAM 12-speed GX Eagle drivetrain ensure efficient shifting and powerful all-weather braking, along with reliability and ease of maintenance. The Bontrager Line Comp 30 wheels and XR4 Team Issue are both tubeless-ready, with the 27.5” wheel size helping to maintain the bike’s handling and ride feel in the smaller sizes. Completing the great value package is a Bontrager Line Dropper seatpost so that the saddle can be lowered or raised instantly on the move via the handlebar-mounted lever, improving speed and confidence on steep and tricky trails.
