GT earned its wings way back in the early days of the BMX race scene and the Speed Series is the culmination of years of knowledge and refinement. Built for the cruiser class, everything about the Pro 24 is fast: the hydroformed aluminum frame, the chromoly fork, the fast-rolling 24-inch Alienation wheels, the hollow-forged GT cranks, and the power-boosting BB30 bottom bracket. Bred for pure racing, the Speed Series Pro 24 sports an integrated headset, chromoly bars and an integrated seat clamp holding an SDG I-Beam post and saddle. The best place to check this bike out, aside from our shop, is on the podium.
