My front wheel was run over, it was not on the bike. There are a few gouges that I sanded down with emery paper. The rim is a little narrower in one section. I assume that this will cause weird braking. I have trued the wheel and it may ride fine

is there any way to fix the rim? like bending it back out?

is there anything elseI should do?

I thought about replacing the rim but it is a Campagnolo Khamsin wheel so it is pretty cheap and I don't know where to get a replacement rim. But to replace the front wheel is more than 50% the cost of a new wheel set.

If the rim was actually squashed so it's narrower in one area the wheel is unsuitable for use. Discounting that it may be weakened, the narrow section will cause pulsing when the front brake is applied. Uneven braking may not seem so serious, but it can cause the front wheel to lock in a hard emergency stop, or cause pulsing which will make controlled descents harder.

While the rim can be aligned, the narrow spot usually can't be restored. If you're unsure how bad it is, mount it and test the braking in a parking lot and decide for yourself.

The time-consuming thing to do is to get a set of calipers and fashion some sort of wedge block that you can drive 'round the rim to re-widen the rim. Otherwise, it will be a frightening situation to stop on this rim. Fix it, ditch it, or it will ditch you.

Take the tire off, tighten a crescent wrench onto the bent section of the sidewall, carefully straighten it back out. I'd pad the jaws of the wrench with a couple of layers of electrical tape, to keep from marking up the rim any worse.

Sounds like new wheel time, the Campagnolo Khamsin is a lower end wheel (for Campagnolo), the time it will take to fix, and risk of failure would make a new wheel a better option

Thank you for the valued opinions, I will get a new wheel set when I return from my tour in a couple of week (I am not taking this bike with me).

I remembered that at the shop I used to work at they had some rim pliers to straighten this type of damage but I never used them and it didn't look like it would work well, or if this tool was intended to be used with steel rims.

Without huge expense and precision machining, I'd say the wheel is toast. Just my opinion.
