I really wanted to like them as I am a tart and have other easton/haven kit but was overwhelmed by the same reports of failures. Even at half price they are more than Hope and your choice of bling rim and spoke.

Weaknesses: HUBS!
the hubs are terrible. the rear hub seperated the pressfit splined female/male interface from the hub body and freely spun it in the hub body, this allowed for a long walk home, Easton did send a new wheel for this!
the bearings are a nightmare, constant replacement
Weaknesses: Reaching the top of Highline in Sedona, ready for the most awesome descent possible, the rear hub blew! As this was only my 6th ride on these wheels,
Weaknesses: The rear hub.
HOWEVER… the guys on here who bash the rear hub are right. Easton blew it on this one
Weaknesses: Hubs! are garbage
The hubs have been totally unreliable. In the three or so months I’ve had them they have been back for warranty twice. My brother has the aluminum havens, same hubs. He has replaced the bearings in the rear hub once already, the wheel is now at easton for repair again.
A friend’s wheels have the same symptoms
etc ad nauseum 🙄
