wheel truing problems

i have a set of shimano WH-R550 on my c-dale. it seems as though the back wheel always goes out of true and even right after i get it trued up at the shop it still won't stay true. any suggestions

Check the tension balance and also the total tension compared to the specifications.

Could your rim be bent?
How much do you weigh?

i don't think it is bend they would of told me and i weigh around 180

I had a lot of trouble keeping those wheels trued - due to the minimal spoking.

Make sure you don't have spokes pulling through the eyelets...

I'd say your rim is warped, and your LBS guy thinks he can straighten it by messing with the spoke tension. Obviously, that's not working for you.

My limited experience with my own wheels says once a rim goes out of true in a major way, it's toast and can't be fixed. Best to either have it rebuilt with a new rim, or pitch it and get something more durable.

I agree with checking spoke tension balance as a spoked wheel is a balance. If your shop trues them and they show true in the stand but when you ride it goes untrue immediately, then they are just tightening or loosening spokes to adjust the runout, but if they don't take tension into account then they won't hold up, the spokes need to ne tight and evenly tensioned (balance) if not those loose spokes will eventually allow the wheel to move out of true again as they are not evenly maintaining tension with the others. I am finding this hard to put into words, but most likely they are not truing your wheel properly, spoke count has little to do with it, mine have 16 and never move.

ok i will check into i actually have not ridden it yet i mean it is not badly out of true like it was before i got it but it is just a little bit b/c you can see it if you look at it compared to say the brake caliper
