As a few others have indicated, I have also rebent a few Cinelli bars for use. It's already been pointed out to trash the bar if there are any gouges or dents to act as stress risers. I'd like to ad;

1) If you think the bend is isolated to a small area (look at the surface texture around the bend for a "crinkled" look) I'd also scrap it.

2) I would also avoid repairing any bend that is at or near the stem clamp area.

3) I would avoid trying to repair ANY heat-treated bar.

4) I would avoid trying to repair bars much under 270-280g range (most of these would probably be heat-treated anyways). This is just my personal guess at a safety threshold.

Handlebars are much cheaper than dental work or plastic surgery. And remember, unless you always ride alone, other riders might be at the mercy of your judgment. Unless the repair is pretty minor, I'd be inclined to toss it anyways. Actually, if you inspect a lot of new bars, very few of them are straight anyways. In any case, if you choose to take a chance, I'm sure you realize all liability rests with you.
