Breaking the barrier to racing BMX shouldn’t cost an arm and a leg. GT's Mach One Pro delivers race-ready specs at a wallet-friendly price to make sure anyone who wants to get into BMX can get on the track. The stiff and lightweight aluminum frame gets all the power from the pedals to the track with a euro bottom bracket for easy bearing changes and sealed reliability. Tubular chromoly cranks spin up lightweight alloy wheels with GT Wing tires delivering solid traction with low rolling resistance. A linear pull brake delivers all the stopping power you need, while GT Uni Pro saddle and GT Race bars keep you piloting with precision.
