GT Bump Bike

Crushing it on the city streets can be just as fun as a long day earning your turn at the local pump track. With the lightweight alloy frame and 8 speed rear derailleur to take you all over Hell's Half Acre and back again, the GT Bump is just as happy slope side as it is in the local skate park.
