Rolf PRIMA ares 4 rim brake

RFS: changing to disc brakes.

Cassette and tires not included


Shockingly light. Blindingly fast.

The Ares4 does it all. With its 42mm Delta rim profile and paired-spoke technology, it perfectly balances aerodynamics with light-weight. You’ll float up long-climbs, save watts on windy flats, master technical descents with confidence and end the day with a smile.

The all-new rim profile features a 20mm internal width and tubeless-ready technology for improved ride quality and compatibility with a range of tire widths. They feature our US-made hubs with Enduro bearings, titanium freehub body and T2 high engagement for instant accelerations and a long life – no matter how hard you hammer. Or, pull out the stops with a ceramic Enduro Zero bearing upgrade for even more speed and longevity.

Disc and rim brake options are available. 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 built by hand in Eugene, Oregon.
