The Radio Solar BMX Race Frame-Purple at J&R Bicycles comes from years of testing to deliver a superior carbon frame that is super stiff and lightweight. Radio built this frame from high-quality Torayca Carbon using a 100% monocoque one-piece design. This allows for added strength by eliminating weak fatigue points. This frame can handle all sorts of high-impact riding styles and has an internal cable routing system which means your set-up stays nice and sleek.
