GT Sensor Expert Carbon Mountain Bike 2020
Borrowing ideas from the bigger travel Force model, the GT Sensor Expert Carbon Mountain Bike is the quintessential trail bike, offering downhill capability and uphill competence, making it perfect for all-round riding. The carbon frame features a flip-chip that lengthens the wheelbase and slackens the headtube by 1/2° to fine-tune the geometry. 130mm of rear travel is supplied by the RockShox Deluxe Select+ shock, whilst the RockShox Pike Select+ Charger RC fork has 140mm of travel to keep the grip levels high and provide control and comfort over rocks, roots and bumps.
The combination of Schwalbe’s 29” Magic Mary Evolution front tyre and Nobby Nic Evolution rear tyre, both in their 2.35” guise, balances great grip with low rolling resistance, and they can be quickly set up tubeless thanks to the tubeless-ready Stan's NoTubes Flow S1 rims. Both shifting and braking are courtesy of SRAM, with G2 RSC hydraulic discs and 180mm rotors giving fingertip control and the 12-speed GX Eagle drivetrain ensuring that the right ratio is always close at hand.
