[Closed] Wheel truing when bent to side at one spot

Our Lord Sheldon and his prophet John proclaimed that ye shalt not re-true wheels by spoke tension, yet verily whack them roughly into shape first then fine tune with spokes.

When a wheel is taco-d (bent to side at two opposing spots) it's easy enough to do this by standing on it and bouncing up and down.

When it's bent to the side at one spot only, that website recommends whacking the wheel on something at that spot to get it straight. Now for all I know this may work fine on a skinny road wheel but such impact is having no impact, so to speak, on my nice tough wide mtb rim.

How do I bend back the offending spot before wreaking havoc with the spoke key?

More force is required.

Is it worth mounting it in the frame, then swinging the entire frame to do the whacking, or will that just destroy the bearings?

Slack all the spokes before you try bending is my tip.

One pumps thetyre up really hard pointing ones misalignment straight ahead.

Then one raises ones wheel above head and strikes the ground with great vengeance.

Alternatively... new bike

Yup, slacken-off spokes to see how much the rim is distorted i.e. it may be the imbalanced spoke-tension that's pulling it out. Slotted drain covers are pretty handy for this kind of 'adjustment' i.e. slot rim in drain and 'firmly' apply pressure

ALL the spokes or just the ones near the bend?

You may as well so them all, since IMO it's better to do a rebuild from zero tension around.

You can just slacken the spokes by the bend.

But getting a decent result is neither easy nor guaranteed.

Well I slackened one that was oddly pulling towards the bend, then

One pumps thetyre up really hard pointing ones misalignment straight ahead.

^^^ This did the trick, thanks!

Alternatively... new bike
