I took my Specialized HR in to the shop to get a complete tuneup, and when it was done, the mechanic told me there was a small dent in the rear rim. It just bulges out very slightly and you can feel it if you rub your finger across it. He also said he wasn't able to completely true the rear wheel completely because of it. He said it didn't look serious and that the rim should last for a long time.
Well, I just read in Bicycling magazine yesterday in the current issue that a little "ding" like that could cause the rim to fail when the brake pad hits it. I thought maybe something could happen if I went over a large bump just as that part of the rim was in the down position, but never thought the brake pad would cause a problem by itself.
Does anyone have a second opinion?
