Radiant Disc Wheelset, Astral Approach hubs
Lightweight, aerodynamic, alloy
The Radiant is a lightweight, aerodynamic alloy road wheelset 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.
Our Approach hubset is built for Astral Cycling by long-time partner White Industries. It includes the same internal mechanisms as their classic CLD hub, but features a bomber heat-treated steel freehub body at a nominal 28 gram weight sacrifice.
All Astral wheels are hand built in Eugene, Oregon USA and feature Tubeless Ready rims you can easily set up at home.
