GT Grade Sport Bike

Escape from the ordinary

For riding everything from forgotten gravel roads to groomed singletrack, this third-generation GT Grade has the capability to take you anywhere you want to go and get you there fast. This redesigned Grade improves upon the previous generations with an updated Triple Triangle™ design, using comfort-enhancing floating seat stays that provide 30mm of “Gravel Travel”, to direct the vibration from mixed-surface riding away from the rider. This alloy frame boasts more tire clearance, and more capability for off-road adventures, letting you have more fun no matter where your ride takes you.

The GT Grade Sport Bike is outfitted to take you on roads that may have seemed previously inaccessible. The Grade Carbon fork features a trio of mounting points on either side for added storage while shaving away grams for added efficiency. The MicroShift Avent X 10-speed drivetrain offers precise, reliable shifting over rough terrain, while ProMax DSK-330 mechanical disc brakes increase stopping power in challenging conditions. A set of the famed WTB Riddler tires on WTB ST i23 rims with Formula hubs keep things rolling smoothly on any surface.
