Thanks for that link. I looked at all of those page links and the photos show damage exactly like mine. I think you guys are correct. I am going to cut a section out and I'll post another two pix or so. Still, what's with that bulge?

As it wears, it will become concave. If it has started to actually bulge then it should be immediately removed from service and replaced because it is in active failure mode. However, the concavity can make it look like the rim is bulging when it isn't. The problem with trying to gauge wear by measuring is that most rim makers do not publish wall thickness. Here's a photo of a rim sectioned like Jan suggests which gives a very graphic demonstration of sidewall wear. The amount of wear can be quite surprising! http://pardo.net/bike/pic/fail-026/000.html On Dec 5, 2011, at 9:26 AM, Jan Heine wrote: > For every rider, it is a good practice to check rim wear from time to > time.
