Mavic Crossride wall of rim pushed in

Just received a Crossride UB back wheel off of ebay. A span approximately 2 inches on the drive side is just slightly pushed in. When I look at the wheel from the top I can see where the gap where the rim strip goes is just a little more narrow.

The tire seems to stay on fine, but I haven't ridden it or even put the cassette on yet. I'll be installing disc brakes once they get here so I don't think this would affect rideability, but I'd like to fix it if possible.

Any suggestions? (besides sending it back)

Well this would be a bent rim or used wheel I am guessing and the spokes are probably off tension on the non drive side in that area from hitting something off camber. This is not repairable without a new rim and spokes. If the wheels is straight and round, but most important is spoke tension of both sides of the wheel and being uniform if you squeezed the spokes at the crossings to confirm. This wheel should be returned as it probably won't stay straight no matter how easy you are on it. Good luck

I wasn't sure if anyone would reply.

The wheel is true. Spokes seem tensioned evenly. The wheel is round. It's just that there is a spot where the rim sidewall got pushed in just a little. I just need a technique to push it back out. I'm thinking a 10lb. sledge and a 2x4 should do it.

Cool well then I have used a 16 oz. rubber mallet in one hand and bracing the wheel with the other hand between my legs and have gotten fairly close on rim brake wheels, but I have not tried this with several inches of area to move. The rims lip is rounded so it shouldn't dig into the tires side wall, or if it's nicked hit it emery cloth or file lightly, so will not cut the tire. Also I have trid the pliers and crecent to straighten and have usually made more damage to the sidewall of the rim from scoring. Good luck

It's hard to tell without seeing the bend. In some cases this type of bend can be straightened by levering the rim wall outward with the aid of a crescent wrench. This needs to be done carefully and slowly to avoid crimping the metal.

I think you'll do more damage trying to fix it.

Return it. Not worth the "maybe" of fixing it. You can get a new front and rear for $199 right now from Jenson.

I sure hope the seller disclosed that damage before selling it to you. Either that or it was damaged during shipping.

Started with a cresent wrench, but could tell right away that would only crimp the bead on the rim. So I braced the rim against my work bench, placed the wood handle of a hammer on it, then hit the handle with a rubber mallet. I worked it gently across the span. It got it back pretty close. Upon further inspection there are four small marks on the outside of the rim where the bend is-so something was likely dropped on it.

Yes, I could have sent it back. But it is brand new and I'm running it with disc brakes, and I got it real cheap (maybe now I know why?). Anyway, live and let live. Thanks to nwbikeman for the suggestions....

You don't say - and probably don't know whether - it is new. It could be the result of excessive rim wear. If it is, the wheel is trash. More than that, the wheel is dangerous. Got micrometer?
