I ruined an almost-new open pro front when I got clipped by some fat guy on an MTB and flew into a curb. Just about pulled one of the nipples through the rim.

I wouldn't get another one for city riding.

(By ruined, I mean it's got a little hop and a little bulging around one of the nipples, so I put it on one of my beaters and will continue riding it until it explodes).
