My rear wheel is slightly out of true and I was wondering how out of true it can be before I need to go get it trued at my LBS.

Slightly out of true is no big deal. Hard to say when it becomes a big deal-- probably depends on quality of wheel parts. I'd invest in a spoke wrench, find a truing tutorial online and just give it a shot. Not as hard as you'd imagine...

truing is one of those issues where the longer you ignore it, the worse its going to get and may cause problems down the line. half a centimeter out is the worst Ill let it get on my own wheels before I take care of it.

I like perfect wheels and once they have been built and trued they really need to be touched... a 5-10 thousandth tolerance is what makes me happy.

Being out of true indicates that there is a problem with a wheel and if a previously true wheel goes out it means that you should find out why this is.... adjusting a minor problem may save you from having to deal with greater problem and only tales a few minutes if you know what you are doing.

Yeah, wheels don't true themselves.


Regarding truing yourself. Yes, get a book and/or get someone with experience to show you. Wheel truing happens in 2 dimensions: up/down & left/right. 3 dimensions if you consider turning the wheel 90 degrees and up/down becomes in/out.

There's an old joke around bike shops:
Q: How do you drum up business for your service department?
A: Give out free spoke wrenches!

I taco'ed a wheel to nearly 90 degrees on my mountain bike once. I'd call that pretty far out of true.

If you can see it's out of true fix it now; as others mentioned, this can save a lot of pain down the line.

It's really not that difficult to do with a little guidance. Sheldon's site has good instruction, especially if you read his info both on wheelbuilding and on truing.
