I ordered a rear wheel from Performance. Mavic MA3 CD(which is anodized) 32 hole with a Dura-Ace hub. On Tuesday I had been checking the true of my wheels and noticed the MA3 was out of whack. Upon further inspection I found that Two spokes had pulled part of the rim apart, just a 1 inch section of the rim. There were longitudinal cracks on each side of the nipples. I weigh around 173 lbs. and don't jump curbs. This wheel had ~1375 miles.
I don't have any experience with MA3s, but I'll bet you dollars-to-dogbiscuits the wheel was machine built, and the spokes were over-tensioned.
