How true does a wheel need to be?

Hi there,

I locked my cyclocross bike to a public stand yesterday, and returned to find it on its side (most likely been kicked over) and the front wheel was very slightly buckled.

This morning I paid a local bike shop to true the wheel. They have done the best they can but it is still ever so slightly buckled -- literally a mm or two. The guy said it will be completely safe to ride, but that I could obviously buy a new wheel. Basically he wasn't very clear in his advice.

Can anyone advise on whether:

a) This is safe to ride?
b) How much efficiency am I likely to lose with a wheel that is very slightly untrue? (If that's even the right terminology!)

I'm basically reluctant to fork out even more money on a bike that I mostly only commute on, but equally I don't want to ride something that is unsafe.

    My rear wheel has been very slightly buckled for a few years now. I have had zero problems with it.

    My wheels have been fairly seriously buckled for a while now, include quite a large 'ding' in the rim. They still hold air tubeless and still go round. It'll probably cost me a DNF at some point but until it does or they get a lot worse I'm happy riding them. Its only a cross bike, designed to get muddy, beaten up and knocked about. A new one will probably look at feel pretty similar pretty quickly.

    As long as it's not causing brake rub and the tyre's not hitting anything you should be OK I'd have thought.

    I trued a very old wheel on a 80s Peugeot bike rescued from a skip using a mixture of brute force and excessive turning of the few spoke nipples that weren't seized. Remarkably still round and true-ish a couple of years on. The spoke tensions must be all over the place, but you can get away with that if you have 36 spokes...

    Thanks, this is all very reassuring! Reckon I'll just ride it for a while and see how I get on.

    I'd think 90 % of bikes in use have more buckled wheels than that.

    100% of the wheels on my commuting bike are more buckled than this!
    Obsessed is a word used by the lazy to describe the dedicated!
