Radio Raceline Quartz Disc Frame


The Radio Quartz Disc race frame is here to solve problems - no more annoying adapters or weird issues when using disc brakes, thanks to their Sliding Dropout Disc System.


Why the Radio Raceline Quartz Disc Frame is awesome

The Radio Quartz Disc frame finally solves the problem all race frames seem to have; disc brakes that require weird adapters, or don't seem to work quite right.

Not anymore.

Thanks to Radio's Sliding Dropout Disc System and use of a flat mount disc brake, the Radio Quartz frame has the most dependable and strong system yet.

With the Paradigm tubing, internal brake routing and the disc system, you'll have one of the lightest, and most stress free BMX race frames on the market!
