Based upon Radio's headlining aftermarket aluminium Quartz frame, their complete race bike is ready to win straight out of the box. This frame has seen six world championships and is constructed from super-lightweight alloy with no details spared.

Radio's designers took this frame and draped it in only the very best components, creating a full PRO build that will hold its own in any level of competition. This alloy frame is no poor cousin to any carbon frames, it's a legit title contender. 

New for 2026, the Quartz Disc frame features the new sliding disc dropouts with flat mount brakes and super stealthy cable routing.
