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 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 wheels are hand built in Eugene, Oregon USA.
