I was in vegas over the weekend doing some seriouse trail riding and I guess I hit a rock and got a nice ding in my front rim. I am a newbie at this since I have not had a new bike in ten years. Is this normal. If so how many of you are riding on a slightly dinged rim and does it affect bike as far as holding air pressure. The tire did not go flat or anything. Do they make stronger rims and how much do they cost. Are there any good websites where I can get a new one instead of selling my first born at the dealer?
