GT Grade Carbon Elite Gravel Bike 2021
The GT Grade Carbon Elite Gravel Bike uses its full carbon frameset construction, intelligent design and robust components to blitz across multi-surface terrain on the biggest of adventures into the wilderness.
The frameset uses an advanced grade of carbon to be both lightweight and responsive under power. The design of the frameset includes the Triple Triangle concept that allows the seatstays to float independently for greater amounts of comfort over rougher paths and tracks. A stable geometry gives balanced handling, but this can be altered by the fork’s integrated flip chip that either increases steering agility or provides more composure in line with forthcoming riding conditions. The frameset's generous clearance for up to 700x42mm tyres promises elevated traction and heightened line accuracy, and a selection of mounting options for luggage carrying make sure the longest rides are well equipped.
WTB ST i23 rims build into a solid wheelset that is set to tackle rough terrain, and their wide inner measurements support the sidewalls of tubeless-ready or standard clincher tyres to grant extra control and decrease rolling resistance. Gear changes are carried out in a reliable fashion by the Shimano GRX 400 setup while the hydraulic disc brakes stop with composure, even in heavy rain.
