From RAAM to a Sprint Tri. Free Speed Guaranteed.
It's the official wheel of Race Across America for good reason. With a 60mm wind-shedding profile and the inherent aero-advantages of a paired-spoke design, these wheels shed wind and go fast all day long. Their low weight keeps them snappy on the climbs and the stiff-yet-compliant ride quality makes them easy to handle and a joy to ride, no matter the ride length.
The all-new rim features a 20mm internal width and tubeless compatibility. The standard Ares6 build features US-made hubs featuring Enduro bearings, titanium freehub body, and T2 high-engagement drive. Or, pull out the stops with a ceramic Enduro Zero bearing upgrade for even more speed and longevity.
All Rolf Prima orders are built by hand in Eugene, Oregon.
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.
