Radiant, Polished Silver Disc Brake only
Lightweight meets aerodynamics meets shiny.
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. The Astral Radiant makes that same technology available for the first time in a traditional laced wheelset. Just like the predecessor, this 32mm profile sheds wind to save you watts all day, while maintaining a low weight for climbing efficiency.
For a limited time we’re offering this spectacular POLISHED SILVER edition. It perfectly combines a fast, modern profile and a classic vintage aesthetic.
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.
