GT Bump Review
GT Bump is the ultimate BMX and mountain bike combo. It has a very light alloy frame and an 8-speed rear derailleur that will allow you to tackle even the most devilish arc. The frames have shorter than average chainstays to they can be handled very tightly. The SR Suntour suspension fork takes the shock out of those super hard landings. The burly GT tires are grip-y and provide easy transition from smooth, city road surfaces to gravelly dirt roads.
