ARES4 DISC

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. 

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. 

*We do our best to ship your wheel order ASAP, but because your wheel orders are custom built, please allow up to 2-4 weeks for shipment once your order is processed.  Contact josh@gkendurance.com for more information!
