Radio Raceline Helium Pro XL Frame (2020) / Silver / 21.25TT

Description

For 2020/21 Radio has really stepped it up with their ever increasingly popular Raceline Helium Frame line up. This Pro XL frame is manufactured from hydro-formed 6061 alloy, riders all around the world have embraced this company's ethos of creating pure race machines that eschew flashy details, and draw upon Radio's German parent company We Make Things experience of producing high quality bicycle parts. One look at these frames in person will convince you of their quality, and a glance at the specs will seal the deal.

Building off a hugely successful first year, the 2020 line of Helium frames gains a healthy injection of exciting new colourways and a new XXXXL size option for riders wanting a lengthier steed. We’re also proud to release our new disc brake mount allowing you to upgrade your Helium Pro frame into a full disc-ready setup in a matter of seconds.

BMX race bike sizing

Race frames are sized by class, and the class you ride is set by rider height rather than age.

SizeRider heightTop tube
Micro (18" wheels)Under 120cm16.25"
Mini (20" wheels)110 to 140cm17 to 18"
Junior120 to 150cm18.25 to 18.75"
Expert130 to 170cm19.5 to 19.75"
Expert XL145 to 170cm20 to 20.75"
Pro150 to 175cm20.25 to 20.75"
Pro XL165 to 180cm21 to 21.25"
Pro XXL170 to 185cm and up21.5 to 21.85"
Pro XXXL175cm and up22"
Pro XXXXL180cm and up22.5"
Cruiser (24" wheels)175cm and up21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

  • Between two sizes and still growing? Take the larger size.
  • Racing gates and wanting the bike to turn faster? Take the smaller size.
  • Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Not sure? Send us their height and we will tell you what we would put them on.
