Straightening rim dints - advice please

[StevieC]

Any one know how?

I've put a moderate dint in my mavic 819 rim due to running them abit too soft with tubeless and pinching the rim on a stone. Tyre still seals so its not a mega dint but enough to make me dislike it so I just wondered if anyone could offer advice on pushing it out / reducing it.
I believe the 819's are quite a hard alloy (in comparison to DTSwiss rims etc) so before I tried bending it back with an adjustable spanner or something similar I thought i'd seek some advice........... hit me

The Morningstar Rim 'Rench was featured in MBA this month. Looks interesting. I also have an 819 with a small dent in the rear. It is causing a small hop as well. Wonder if I straighten the rim wall, if it will also straighten the hop?

I think I'm going to order one soon.

I tend to use an adjustable spanner to prise the dent out and then find a piece of wood/metal the same width as the inner diameter of the rim (placed inside the rim) to allow me to hammer (wooden or use a soft drift) the rim gently against to straighten it out

+1 One of the few things I use an adjustable spanner/crescent wrench on...

Just Don't mess with it too much, the aluminum tends to crack on these rims on the inside of the crease. Just bend it back with a spanner and say good enough, I could see a leak forming on the inside of the rim if it is tampered with too much. Cheers.

Regular pliers with some terry cloth or other thick cloth to avoid scratching.

Someone mentioned feeling wheel hop. Time for a complete wheel true, that's from irregular spoke tension and a bent rim, more damage than a dent.

If the tire seals and pretty true, I would do nothing. Wear that dent as a badge of honor.

If not, I've used the above method with an adjustable wrench and all came out well. That morningstar tool look great, and worth the price if it works as well as MBA reports.

it may be in french but the pix speak volumes.

I tried the crescent wrench jive and it don't work - that is unless you want another dent midway in the sidewall. The inner wall of the rim prevents it from getting low enough to lever correctly.
I ordered one of the specialty wrenches - will keep you informed.
