About This Product
The GT Performer 18in BMX Freestyle Bike-Purple at J&R Bicycles features an upgraded spec with high-end components but without the high-end price point. Beginner riders deserve a quality start to their BMX journey which is exactly what the Performer 18" has been designed for. The updated frame is made from 100% Hi-Ten steel tubing and features an integrated headtube with sealed Mid bottom bracket. This sturdy frame, chromoly 3-piece cranks and big soft tires are built for smooth performance while being able to handle the dings that come with the learning process.
