Rolf Prima Ares4 Carbon Clincher
The draw: Super light for light riders
With one of the lowest-profile rims in the testing pool at 42mm, it’s no surprise that the Ares4 is also one of the lightest of the group. The low spoke count also reduces weight, while providing an even lower side profile—ideal for super windy days or super light riders. Heavier riders putting out massive watts may find the Ares4 a bit on the softer side, but when the hills point skyward, the lightweight ceramic bearings will undoubtedly bring relief. Aesthetic bonus: Rolf offers a rainbow of decal and hub color options to fully pimp your ride.
