A low-maintenance, technique-driven bike for riders looking to improve their freestyle skills, the GT Slammer gets you out sessioning the streets without emptying your wallet. Work on your style, work on your technique, dial-in your transitions. The Slammer's got your back with durable parts and a detangler so you can gain that extra margin of safety with brakes but without them getting in your way.
