    so the hub is in properly but the rim and tyre isn't centred? If so, it sounds like it isn't correctly dished.

    I can't think of how to explain it but know how it works. you know that their are spokes on the left and right side of the hub. It's basically there beng too much tension in one side so that it pulls the rim that way.

    Wait for Supersonic to arrive, he'll explain it properly.

    the tension will have gone out of the spokes and it needs sorting. common issue with some OE built wheels.

    LBS time.

    Take it back to the shop, no point in potentially invalidating your warranty filing any burrs in the dropouts or something. And don't ride it in the meantime - if the forks are bent it might not be safe,

    What wheel, what bike, what forks?

    I have the same thing with my front wheel. It sits a few millimetres to the disc side. I checked the spoke tension rather crudely by pinging them with my finger and they all seem tight pretty tight. I've left it like it is as I wasn't confident my LBS would be able to redish it properly may just make the wheel worse or introduce some other problem.
  • no need for LBS, there are youtube guides online. get hold of a spoke key and give it a crack! thats what i do and i have never had any issues, harmless DIY job.

    I disagree with that, wheel truing is bar far the easiest job you can make a total hash out of on a bike. It takes the proper tools (truing stand + spoke tension meter) or lots of experience, preferably both. Get it wrong and your wheels will go out of true quickly, and you'll start bending rims and snapping spokes.
  • maybe, depends how confident you are doing the job, i dont think the theory behind it is too hard though, but thats just my opinion.

    'Kene', take a look at this (no. 12); http://www.bikeradar.com/mtb/gear/artic ... eels-28949

    that should explain it a bit!

    Sounds like the fork lowers might be slightly bent - it only takes a fraction of a mm at the axle to displace the rim by 3mm.
    In addition to what you have done already, you can check if the wheel is dished by mounting the wheel into the dropouts 'backwards', i.e. with the disc rotor on the wrong side. If the rim is now biased the other way, the wheel is dished. If it biases the same way as before, it's the forks.
    I've seen this before, and as I was sure the forks were not cracked or seriously damaged I just solved it with a DIY shim: cut a strip of aluminium about 4mm wide and 100mm long from an oven-ready meal tray, folded it over itself lengthwise in roughly 15mm increments until I had the right thickness (it took about 4 folds), cut off the surplus, and wrapped it around the axle to give it the right 'U' shape. Stuck it in the drop-out, mounted the wheel - problem solved. (Just had to be careful not to lose the shim when I took the wheel off :) )
