The helium frame took the race world by storm when Radio released it almost x2 years ago. With multiple world championship wins, the helium frame is now a common site on tracks across the globe. For this season they wanted to give the helium a full revamp. Radio’s flagship frame now uses their very own new 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!
