The Radio Bikes Quartz Disc Frame is the next evolution of Radio's world championship-winning BMX race platform. Featuring the all-new Sliding Dropout Disc System (SDDS), this disc-brake-specific frame delivers outstanding performance, precise chain adjustment, and exceptional stiffness in an ultra-lightweight package.

Constructed from hydroformed 6061 alloy Paradigm tubing, the Quartz Disc Frame is engineered for maximum efficiency, responsiveness, and speed on the track. Internal brake cable routing keeps the setup clean and protected, while the forged and CNC-machined SDDS with integrated chain tensioners ensures easy wheel alignment and compatibility with both 10 mm and 15 mm rear axles.
