Radio Race HELIUM JUNIOR

The Helium Frame took the race world by storm when we released it almost x5 years ago. With multiple World Championship wins, the Helium Frame is now a common site on tracks across the globe. Our flagship frame uses our very own forged dropout design which allows it to be fully disc-brake compatible when used with our Helium Disc Brake Mount. Available in a huge variety of sizes and some of our most vibrant and unique colours to date, there simply isn’t a better looking or feeling frame on the market than the Helium!
