The GT Bicycles Men's Grade Carbon Pro Road Bike was engineered to take you further and faster, the Grade is more compliant, versatile, and adjustable than ever before! The Grade Pro is equipped with a flip chip fork to provide 15 mm of adjustability. This allows riders to go from 55 mm to 70 mm of fork offset. Run the 55 mm offset for gravel races or flip to the low- trail 70 mm offset when youre loaded up with cargo on a bikepacking adventure. The Grades seat stays are comprised of two lightweight fibers: a tough composite of carbon and fiberglass. The solid fiberglass core provides toughness and damping, and the carbon fiber outer layers act to control stiffness. In the end, you have a bike that gives the rider a lot more control and less fatigue on the ride.
