|Is my wheel salvagable?||JVG|

|I had a small accident this week where I slammed into a guardrail at about 30 mph during a descent. The bike came away unscathed, save for a cut on the bar tape and a dropped chain. I suffered the brunt of the impact (helmets really work when they are worn!!) and I was able to ride home after opeing up the brake calipers as the wheels came a little out of true.
Upon closer inspection, I see that I have a dent in the front rim about 1/8 inch deep and about 3/4 of an inch long. It is right on the lip of the rim. Is this rim repairable, or am I looking at purchasing a new front wheel?

|I've hammered dents out of lightweight rims. It won't be perfect but sometimes it works OK. It works better on wheels with wider tires.|

|If the the dent turns into a crack after a few more rides, then it's toast. In my opinion, a rim's structure needs to always remain intact, in order for it to perform all of it's duties. 1) hold a highly pressurized tire, 2) take side pressure from brake calipers 3) hold rider's body weight 4) stay strong to hold tension from the spokes.
A rim has many jobs. And if you're riding a light weight racing rim, atleast one of these jobs aren't going to be done to it's full extent.
Also, you might have uneven wear on the rim, and develope spots where the brakepads will contact the rim more than others, and in the dent, it won't contact it at all.
Your hub perhaps is still salvageable, but your rim seems otherwise. Maybe rebuild the wheel using your current front hub on a new rim.
Hope any of this helps.
Just my 2 cents,

|Thanks for the advice guys. I think you confirmed my suspicions. The wheel is a Campy Proton, so there's not much mass there to work with in terms or hammering out the dent. Also Andrew's comments about the rim permorming different functions (particularly braking) tells me that I am just asking for another accident if I keep using this rim.
I guess I know what to ask Santa to bring for Christmas.

|without the wheel in front of me. Got a digital camera? The lip of the rim plays a very important part of the wheel system. Even more so on road bikes with high tire pressures. If the lip is bent to far in then it won't accept the tire bead. You don't want that tire blowing off the rim in that same turn. My 2 cents, get it replaced. I'm gald your ok. Paul|| |
