Rolf Prima Ares4 ES Wheelset
Details
Lightweight Aero Performance
The Ares4 ES does it all — at a price point that avails the world of pure speed to more riders. With a 42mm Delta rim profile and paired-spoke technology, it perfectly balances weight savings with aerodynamics. Float up long-climbs, save watts on windy flats, master technical descents with confidence, and end the day with a smile.
The updated rim profile features a 19.5mm internal width and tubeless-ready technology for improved ride quality and compatibility with a wider range of tire widths. It’s coupled with our solid, yet economical 3.0 level hub for smooth rolling performance mile after mile.
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.
