I was riding my old x-mart bike tonight, and hit a stump off a little jump, and noticed there was a buit of a bulge out of the side of rim. The are alloy, and pretty cheap, so how should i fix it? Is it worth taking to my LBS or can i do it myslef? How can i do it if so? :beer:
Know anything about removing dents in a fender using a Dolly and Hammer? The same idea applies to the rim. Put something hard and shaped somewhat like the inside of the rim, and tap --I said, TAP, not hammer-- until it is smooth again. It won't come out perfect, but if you're careful, it can be fairly close.
Remember, though, that the wheel will never be as strong as it was before you mangled it.
But, if you are going to continue jumping, you would be doing yourself and your family a favor by investing in some wheels that are made for that kind of abuse. It may save you a trip to the hospital.
Also, if yu ever move on to something a little better than the x-Mart special, You can transfer the the same good wheels.

Thanks, I thought I could fix it that way, just wanted to make sure. And BTW i don't normally ride an x-mart bike, I traded with my brother for that ride, and there was a large stump where i landed. I'm surprised I didn't do more damage. :beer:

I would ease it back into place using a large adjustable spanner (monkey wrench), rather than tap it.

I never thought of that:rolleyes: Sounds like it might be easier on this rim.
I don't think Alloy rims take well to the crescent wrench repair, but let us know how it turned out.
Anything you do with a hammer or a wrench or a vise or any other gripper is going to leave a permanent dent in the outside wall of the rim.
The best thing I have found is to put two thin pieces of hardwood on both sides of the damaged rim area. Fit a large C-clamp onto both sides of the two pieces of wood and squeeze the dent back into place. Works good without noticeable damage.
