Radio Raceline Quartz Frame Matt Black

Brand 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. Available in x6 sizes and in our super stealthy matt black finish, the Quartz is guaranteed to be the lightest and sleekest machine on the track…
