Radiant & Radiant Disc Rim

Lightweight, aerodynamic, alloy The Radiant is a lightweight, aerodynamic alloy road rim good for any occasion.  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. The Radiant applies that same engineering and testing, now in traditional lacing.  Just like that predecessor, this 32mm profile sheds wind to save you watts all day, while maintaining a low weight for climbing efficiency. All Astral rims are Tubeless Easy for pain-free tire installation that you can set up with a pump at home.   Custom builds available! Any hub, any spec, just contact us with your special project.
