While many prioritize low weight in the name of climbing speed, there’s more to a great wheel than its 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.

This famous rim is laced to hubs from our long-time USA-made partner, White Industries. All Astral wheels are hand-built in Eugene, Oregon and feature Tubeless Ready rims you can easily set up at home.

Tubeless technology

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.

Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.

UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
