I'll pull the Ultegra skewers off tonight and compare them closely to the ACs to see what differences there may be. The rear wheel seemed a little "looser" with the AC skewer, but not nearly as pronounced as the front. I can literally wiggle the front wheel from side to side so that it touches the brake pads when it's locked in with the AC skewer...weird. I'll take some pics and post them if I can't figure it out. Hard to believe the AC skewers aren't working with the AC wheels! The fork is a carbon Wound Up on my Waterford ... nothing out of the ordinary going on with it and it's never been a problem before, so it must be the skewer.
