Description

The wait has definitely worth it! The all new Radio Terra Pro Frames are available and ready to be built up for the new season of racing. Manufactured with proven material technology TORAYCA carbon fibre, they look sleek with their flat mount disc braking system (with internal hose routing), and laid up during their construction process in a way that provides superior stiffness around the crucial area of the head tube and bottom bracket. 

Race proven already with Australian Teya Rufus winning the Women's 2024 Junior Elite World Title on a prototype, we expect that this new frame from Radio will be seen on plenty of podiums from 2025 and beyond. 

Features
  • Full monocoque TORAYCA carbon. Laid up for extra stiffness around the head tube and bottom bracket, and laboratory tested for strength to weight.
  • Flat mount disc, internal hose. Disc specific, so no v-brakes: designed for 140mm and 120mm rotors with the hose routed inside the frame.
  • Sliding dropout disc system. Forged and CNC machined SDDS dropouts with integrated chain tensioners give 30mm of adjustment and take 10mm or 15mm axles.
  • Steeper head tube, shorter back end. A 74° head tube angle and 71° seat tube angle for a snappy, responsive feel out of the gate.
  • 21.75" top tube, 14.3" chainstays. Pro XXL fit on a Euro threaded BSA 68mm bottom bracket, with clearance for tyres up to 2.0" (50mm).

BMX race bike sizing

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

Micro (18" wheels)Under 110cm16.25"
Mini (20" wheels)110 to 125cm17 to 18"
Junior120 to 140cm18.25 to 18.75"
Expert135 to 155cm19.5 to 19.75"
Expert XL150 to 165cm20 to 20.75"
Pro160 to 170cm20.25 to 20.75"
Pro XL165 to 175cm21 to 21.25"
Pro XXL170 to 185cm and up21.5 to 21.85"
Pro XXXL175 to 185cm and up22"
Pro XXXXL185cm and up22.5"
Cruiser (24" wheels)175cm and up21.5" and up

Heights overlap between bike sizes on purpose. If you fall in two size categories, a growing rider new to racing is usually better suited to the larger bike, a experienced rider who wants the bike to more responsive should err on the smaller size. 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. Just don't guess their height either, you know how fast they can grow!

Here are some tips

  • Between two sizes and still growing? Take the larger size, but make sure you check the top tube length of the bike. The length of top tube for a given size (Expert XL as an example) can vary up to a half inch or more across brands. Most Expert XL frames are 20", but we've seen them as long as 20.7"
  • Experienced racer and wanting the bike to be more responsive? Take the smaller size. You want the bike to be "under you", not a stretch to the bars and cranks.
  • Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Still not sure? We're the experts and size bikes for riders every day of the week. Our team has decades of experience between them and will help you decide which bike is the right fit based on rider height and racing experience.
