Description

Radio Bikes didn't hold back when they brought out their very first carbon BMX race frame and completely crushed it with the Solar range. Designed and developed in Cologne, Germany, the Solar frame is manufactured from Torayca carbon and is a 100% one piece monocoque construction producing one of the lightest and stiffest BMX race frames on the market. Most race frames on the market use a blended two, or three, piece construction method to save on costs, but not Radio. This company has stepped up and produced what we think is one of the finest carbon race frames available.

Touches like internal cable routing and a Euro bottom bracket add to the value of this frame when analysing performance at this end of the market. The majority of carbon frame manufactures choose the easier route when it comes to the bottom bracket, opting for a BB86 style. A Euro BB is more complex to incorporate in the manufacturing process, though it arguably produces the stiffest result in an area where it's required most, the start of the powertrain. 

The Radio Solar Pro XXL frame would form the basis for one of the best performing custom race bikes you could build. Hit us up at LUXBMX and we can bring all of the parts together for you to make the race bike of your dreams a reality. Dialled in with the most desirable components available on the market today. 

Features
  • One piece carbon monocoque. Radio built the Solar as a full monocoque instead of bonding two or three pieces together, making it one of the lightest and stiffest race frames available.
  • 1.160kg on the scales. TORAYCA carbon keeps the Pro XXL light, and the frame is laboratory tested for strength and stiffness.
  • Euro threaded bottom bracket. Harder to build into a carbon frame than a BB86, but arguably the stiffest result right where the powertrain starts.
  • Internal cable routing. The brake cable runs inside the frame, keeping the line tidy and out of the way at the gate.
  • Pro XXL race geometry. 21.75in top tube, 14.25in minimum chainstay, 74.5° head angle and 71° seat angle, on 15mm dropouts.

BMX race bike sizing

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

Mini (20" wheels)110 to 125cm17 to 18"
Junior120 to 140cm18.25 to 18.75"

Pro160 to 170cm20.25 to 20.75"

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.
