Lightweight meets aerodynamics in alloy

While many prioritize light-weight in the name of climbing speed, there’s more to a great wheel than their weight. An aerodynamic wheel makes you faster in all settings, not just when the road points up, and as the Radiant proves, you don’t have to sacrifice one for the other – even in an aluminum wheel.

Rolf Prima pioneered the aerodynamic alloy wheel market 20 years ago with the Vigor – a now classic best-selling rim profile that is noticeably faster than its low-profile competition but just as light. With the Radiant, you can now build that same performance to any build you imagine.

Just like it’s predecessor, this 32mm profile cuts through wind to save you watts all day, while maintaining a low weight for climbing efficiency. It is drilled for external nipples and available in rim or disc brake versions. Disc brake option is all-black.

All Astral rims are Tubeless Easy for pain-free tire installation that you can set up with a pump at home.  

Add a nipple kit for an easier build. Choose the Radiant as a complete wheel build.
