My rear rim has failed on my Trek 6700. It's a Bontrager Superstock rim (28 spoke), and it's flared out on both sides of the valve stem in a most bizarre fashion, to the point of nearly locking in the brake pads. Disappointing, because I only had about 1,100 miles on the rim, almost all on-road. It may have been caused by hittling a pothole, but I don't recall anything disasterous.
I had to commute home tonight with the rear brake disabled. At home, I trued it, and tried to bend the flare in the rim on one side of the valve stem back straight. I then trued the wheel fairly well, and reinstalled. Soon as the tire was back to recommended pressure (Armadillo), the rim had flared and locked in the pads again, apparently on both sides.
So, if I'm commuting about 80 miles a week on this bike, and I like to take it on fireroads and some trails in the summer on vacation, what would you recommend as a good replacement rim. I don't want anything too flimsy. Also, I'm tempted by the ceramics, since I ride in the rain a fair deal, and I wouldn't mind better stopping power-- but are they reliable enough for heavy use.
It also crosses my mind that my choices may be limited since my rear hub is a 28 hole, although I could replace it with an XT 32 hole.
