Ultra-lightweight & fast 

The new Eos4 takes the Eos3 deeper for riders looking for the best combination of aerodynamics and weight. We’ve taken our US made TdF7.0 hub platform that includes our T2 high engagement drive mechanism for immediate engagement and top of the line Enduro XD-15 ceramic bearing and paired it with a new 42mm deep, Delta profile, tubeless compatible, carbon clincher rim. At 19.5mm internal width, the Eos4 is designed to be fast and handle well in all conditions and be versatile for tire size options.

Looking for a Disc brake option? Choose our Ares4 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.
