The Radio Helium frame has been out on track now for 5 years, with each year seeing the brand steadily improving this frame. For 2025 the colours and graphics have definitely taken on a clean look, with solid colourways and bold Radio decals on the down tube.
Technically, the frame is manufactured from industry trusted hydroformed 6061 alloy tubing, which produces a super lightweight race frame that is strong enough to take on the big tracks and high speeds they produce. Even the youngest racers need a frame that can take on 5m hill and everything that follows on from it.
The Radio Helium frame has proved over the past 5 races seasons that they can not only produce race wins, they are built to a standard where you can trust it with touches like a forged (read strong) dropout that can integrate Radio's disc mount. Or if you're running V-brakes, then Radio has you covered here as well. You have the choice.
