Track-tested to perfection
The Helium 20" is the first aftermarket race frame in Radio's race line. It has been tested on a race track and optimized over and over again by a team of experienced race riders until the result was spot-on.
Super light and ultra strong race frame
- Super light and hydroformed construction made from 6061-T6 aluminum
- Incredibly stiff rear end thanks to its special tubing
- Solid 20mm dropouts with included chain tensioners for 10mm, 15mm and 20mm
- Warm up and cool down with ease thanks to its Promax quick release seat clamp
Notice: Available in a choice of sizes to fit every rider.
