Radio BMX Raceline Quartz BMX Race Frame - Pro 20.5'' TT Matte Black Model=Coil Spring Spacer Kits Cassette Cogs 11-12-13-15-17-19-21-24-28 Color SilverBrand new for this season the Quartz frame is a x2 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.
