The GT Speed Series Pro is a serious race BMX bike for the rider that is looking to compete at their best. A serious racing bike starts with a seriously good frame and GT have delivered the goods with a 6061 Alloy Elite Race Design Frame which is paired with a 100% Cr-Mo tapered fork for the ultimate control and speed on the dirt. You'll be able to pump out plenty of power through the GT Forged Alloy 2 piece cranks and get up to top speed while you're rolling on the durable Aero double wall rims and Kenda Kompact Pro Race Tyres for the ideal blend of speed and reliability. When you need to control that flat out pace into the corners you'll be well looked after thanks to a rear Promax Hydraulic Disc Brake which gives you excellent stopping power. The GT Speed Series Pro delivers race brilliance straight out of the gate, with every aspect optimised for maximum race-day performance.
