Ares4 FX

Description

Fixed Fast

The Ares4 does it all. With its 42mm Delta rim profile and paired-spoke technology, it perfectly balances aerodynamics with light-weight. Based on our best-selling carbon profile, the new fixed-gear edition float smashes climbs, cuts wind and confidently handles technical riding - be it in city street, quiet country climbs or the velodrome. 

Featuring US made fully CNC machined high flange hubs carbon aero rims, this is the swiss army-knife of track wheelsets. 

All Rolf Prima Wheels are hand-built in Eugene, Oregon.
