Hey, the other night be and my friend were out in his front yard using the trials stunts we built. My friend thought he could hop OVER our bar thing gap about 3 feet of road on to the curb. He Gaped it allright but his back rim didnt, he smashed it on the corner of the curb and put a BIG ASS flt spot in it. Now what im wondering is is it possable to get rid of a flat spot.:help:

It is possible - to a degree. First, the wheel would have to be de-built. With all the spokes removed, a tool (basically a press around a curve) would 'pull' the rim back into some semblance of round. Unfortunately, after this is done, a small crease usually appears in the rim. This tool is used for extreme cases, albeit not a perfect solution.

I flat spotted a road wheel once. I detensioned it, removed the spokes in the flattened area. Then, using a piece of oak in a big vice and a large rubber mallet, I massaged it back into round. I relaced the area and retensioned it. Rode it for three more years.
This is a lot of work but it was a vintage, out of production rim, on an older bike.

How flat are we talking?

you can usually retension a wheel to get a pretty decent flat spot out, but in the end, if it's bad enough, you may as well replace it.

Aluminum doesn't take rebending well without heat treatment. It tends to get work-hardened and brittle at that point.
