GT Slammer BMX Bike









- The Slammer has the aspiring Olympic skatepark rider in mind. The frame's geometry is quick responsive allowing the bike to handle easier as the young rider builds up their strength. Items like a cable detangler, sealed mechanism 14mm axle, 9T cassette hub, and adjustable railed saddle are the little details that will allow this future champion to practice with confidence.
