GT Force Expert Carbon 27.5" Mountain Bike 2020
The GT Force Expert Carbon Mountain 27.5" Bike is based around a 150mm travel frame and 160mm FOX Float 36 Performance Elite fork, providing the perfect chassis for gravity-inspired riding, with the addition of a flip-chip allowing the geometry to be fine-tuned to personal preference. 27.5” wheels add to the bikes handling credentials, keeping it agile and nimble for picking the best lines at speed. The combination of Schwalbe 2.35” Magic Mary and Hans Dampf tyres inspires confidence thanks to their prodigious grip, whilst they are ready to be set up tubeless with the rugged Stan's NoTubes Flow MK3 rims if required.
GT’s own Dropkick Dropper seatpost with handlebar remote lets the saddle be instantly lowered for extra manoeuvrability and the large rotors help the TRP G-Spec Trail S hydraulic disc brakes work tirelessly all session long. Finally, SRAM’s 12-speed GX Eagle drivetrain has sufficient ratios not only to fly downhill, but also to make the ascent less of a chore, with a 10-50t wide-range cassette and 32t chainring.
