Aerodynamic Carbon Rim Brake Clinchers Handbuilt in the USA

The Rolf Prima Ares4 Carbon Rim Brake Wheelset is designed to cut through the wind on its way to victory. Combining wind-cutting paired spoke technology and Rolf's Delta rim profile, this rim brake-compatible wheelset provides feather light aerodynamics and responsiveness.

At 42mm of depth, the carbon fiber rim is firmly in the mid-profile realm, but provides aerodynamics comparable to much deeper wheels on the market. With an external width of 28.5mm, the Ares4 offers an optimal pairing with the day's wider road plus tires for improved handling and aerodynamics.

With Rolf Prima's TdF4.4 hubset, this version of the Ares4 is compatible with rim brakes. Inside, Enduro's steel bearings keep the hubset spinning effortlessly. Rolf Prima's T2 High Engagement drive mechanism delivers instantaneous engagement.

The Rolf Prima Ares4 Carbon Clincher Wheelset includes rim strips, valve extender, and QR set when applicable.
