GT Bump 20" BMX Bike - 2014Ride it hard. The GT Bump 20" BMX is designed from the ground up to handle the toughest trails and the wildest jumps. As the name implies, this is not a bike that will run from the rough stuff. Heading for a street session? Just add a set of pegs and the GT Bump is ready.
The GT Dirt Design Frame with Cr-Mo Main Tubes and the Cr-Mo steerer fork are light, strong and stiff. Just what you need from your first run to your last, as the sun goes down. Carefully selected components compliment the frame and fork and begin with a rugged, lightweight GT Tubular 175mm Cr-Mo 3-piece crank with Cr-Mo spindle. The 25-tooth GT aluminum chain wheel is matched with a 9-tooth cassette for a compact drivetrain that gives extra clearance and saves weight. The Tektro FX340R rear U-brake with Tektro 289A lever delivers precise and powerful stopping.
The 36h double-walled rims, with front and rear alloy hubs can, take a hit and are matched with a mixed set of tires; the GT Dirt Tread front and GT Pool Street Tread rear, deliver traction and control in the dirt and speed on the street. The Pivotal padded seat and pivotal post make for a strong and light combination. The taller handlebar gives more leverage and control.
