 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.

The Stage 1 hubset is custom made for Astral Cycling to provide a reliable, strong and light wheelset option. They’ll see you through all your adventures without breaking the bank.

All Astral wheels are hand built in Eugene, Oregon USA and feature Tubeless Ready rims you can easily set up at home.
