GT Force Expert Mountain Bike 2020
The combination of a long travel chassis and 29” wheels guarantees that the GT Force Expert Mountain Bike will be an extremely quick bike to ride downhill. The FOX Float Performance DPX2 rear shock has 150mm of travel, ensuring that the rear wheel has maximum grip at all times, and with 170mm on offer from the FOX Float Performance 36 fork no drop or jump is too big to tackle. Large rotors help the power and performance of the TRP G-Spec Trail S hydraulic brakes to match the rest of the bike, providing control and confidence when needed most. GT’s own Dropkick dropper seatpost gets the saddle out of the way when required, and the geometry can be fine-tuned using the frame’s flip-chip.
29” wheels roll better over obstacles, with the tried and tested Maxxis Minion tyre combination gripping reliably in a range of conditions. Gear shifting duties are performed admirably by SRAM’s NX Eagle shifters and derailleur, giving quick access to the 12-speed 11-50 ratios on the cassette.
