Helium 20" Race BMX Stel

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.
