Radio Race HELIUM PRO L

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!
