I got a set of Open Pros with Dura Ace hubs I just put on the bike, and the rear hub makes a pulsating click (as opposed to the rhythmic even tempo click some pawls make when freewheeling). This is on the stand, not even riding yet, and not the noise some OP rims have from the weld- its the hub for sure. Are DA hubs usually quiet when they freewheel? Even if not, a pulsating noise from the hub can't be right, true? Any input appreciated before I pull my cassette and send it back.
