Radio Raceline spent over three years developing the Helium, their first aftermarket race frame, testing it on the track and designing it alongside a team whose BMX race knowledge spans three decades. It is built from hydroformed 6061-T6 alloy, with tubing chosen to keep the frame light and responsive while the back end stays incredibly stiff.

This is the Expert XL in Lime Green with a 20.5" top tube. The dropouts are forged and CNC machined with an integrated chain tensioner, it takes a disc brake using the Helium Pro disc brake mount, and every frame comes with a Promax quick release seat clamp so you can change seat height when you need to.
