Picked up a ding on the rear rim whilst out on the trail yesterday (one side only) - will it knock back into shape and if so what's the best way ?....

.... or is it a new rim ?

I'd leave it, doesn't look to bad.

It'll be fine, next time you fit a new tyre, use a dolly and hammer to massage it back into shape, have a good look for cracks though.

Make sure you check for any loose spokes as there may be a few.... Tighten accordingly .

Use a little heat when straightening aluminum, or there is a good chance it may crack.

Do you have a hydraulic press?

I don't have a shop press Jim, but I'm sorely tempted https://www.ebay.co.uk/itm/6-Ton-Hydrau ... Sw7aBVDNgL

I can't believe how cheap they are - ok, it'll probably be a Chinese import.... and it probably wouldn't stand up to dealer workshop use.... but for occasional home garage use... what could possibly go wrong

Only problem for me is - with 5 bikes and an old sports car in need of renovation, space is getting a bit tight in my garage

An hydraulic press is a very useful tool. With your toys you should have lots of use for one, however I predict at some point you will be disappointed with only 6 tons pressing capacity.

I have a 20 ton press, and even with that much capacity it doesn't always do the work I need done.

When it comes to presses, I recommend you get the biggest you can afford or have room for.

With five bikes and an old sports car in need of renovation...you need a hydraulic press. All kidding aside, they're definitely useful tools. I have a 20-ton Harbor Freight/Chinese press, and it does what I need it to do. Nowhere near professional shop quality, but it works. I definitely agree with pumpguy - buy bigger than six tons.

I wouldn't buy a new rim if that was my bike. (As long as the one you have isn't cracked.) I've had decent luck straightening them out a bit with a press. Be careful/patient, obviously don't go too far and make things worse than they were to begin with.

The trick is to convince a friend that he needs one.
