Radio Quartz BMX Race Frame – Matte Black


Radio Quartz BMX Race Frame – Matte Black



SKU: N/A Category:

Brand new for this season, the Quartz frame is a 2X World Championship winning super light alloy race frame. Taking our track-proven Helium frame as a base, we upgraded the frame to use our new Paradigm 6061-T6 hydroformed superior tubing to shed a considerable amount of weight compared to the Helium frame. The Quartz also uses our new forged dropout design which allows it to be fully disc-brake compatible when used with our Helium Disc Brake Mount.
