Rolf Prima Eos3


The Eos3 has been updated to a 32mm deep, 19mm internal width, tubeless compatible carbon clincher rim to deliver race-ready weight and ride performance. The Eos3 features our top of the line, US made TdF7.0 hubset, including our T2 high engagement drive mechanism for immediate engagement and top of the line Enduro XD-15 ceramic bearings. As with all of our wheels, these are built by hand in Eugene, Oregon.

Looking for a Disc brake option? Choose the Ares3 Disc with a 7.0 Upgrade for a hub platform with the all-conditions stopping power of disc brakes. Both rim and disc brake models are tubeless compatible. Add our Basic Tubeless or Full Tubeless kit to your order and you’re ready to go.
