Light-weight Aero Performance. 

The Ares4 CS 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 20mm internal width and tubeless-ready technology for improved ride quality and compatibility with a wide range of tire widths. It’s coupled with our solid yet economical 3.4 level hub for disc brake for smooth rolling performance mile after mile. For the best performance in every case, go all-in with the standard Ares4. 

Disc brake only. Add a tubeless kit to your order and you’ll have what you need to get set up in a snap.

All Rolf Prima orders are by hand in Eugene, Oregon.


*We do our best to ship your wheel order ASAP, but because many wheel orders are built to order, please allow up to one week for shipment once your order is processed.  Custom orders like color hubs, rims and decals may take up to two weeks.
