THE RADIO QUARTZ FRAME IS A x2 WORLD CHAMPIONSHIP WINNING, SUPER-LIGHT, ALLOY RACE FRAME. USING THE TRACK-PROVEN HELIUM FRAME AS A BASE, RADIO UPGRADED THE PLATFORM TO USE THEIR NEW “PARADIGM” 6061-T6 HYDROFORMED SUPERIOR TUBING TO SHED A CONSIDERABLE AMOUNT OF WEIGHT COMPARED TO THE HELIUM FRAME. THE QUARTZ ALSO USES A NEW FORGED DROPOUT DESIGN WHICH ALLOWS IT TO BE FULLY DISC-BRAKE COMPATIBLE WHEN PAIRED WITH THE HELIUM DISC BRAKE MOUNT. THE QUARTZ IS GUARANTEED TO BE THE LIGHTEST AND SLEEKEST MACHINE ON THE TRACK
