Rear Wheel Positioning.

Hi guys,

I've just got my rear wheel back from a bike mechanic friend after having it trued. I notice that the wheel seems to sit offset to the left hand side (when viewed from behind with the bike upright) at the area of the bottom bracket. The wheel looks perfectly central to the frame at the top at the brake area but looking down it sits closer to the frame (rear triangle) on the left hand side.

I have checked and re-checket that the wheel is seated correctly into the mounts.

My bike is a Bianchi Nirone 7. And as you can guess.....it's my first road bike!

Thanks,
Mark

    I have just realised that i've made a complete fool out of myself with the question. Of course it will sit closer to the rear left triangle than the one on the right, as the one on the right is further out to accommodate the rear cassette.

    Errrm.... No!
    That's why wheelbuilders 'dish' the wheel!

    I'll load my rifle, now, incase I've got it wrong :shock:

    The RIM should be in the centre, the HUB SHELL will be offset to the left to allow space for the cassette body (when looking from the back of the bike obv).

    If the rim is offset then the wheel hasn't been dished properly and the guy is no wheelbuilder.

    Thanks for your help guys. It really didn't look right when I put the wheel back on - but been a novice you just don't know. Thank the lord for the internet eh?

    To the LBS it is......

    Take the wheel out and put it in the other way round. If the rim is still offset left then the wheel is OK. It is the frame that is out a bit. If the rim is central at the brake bridge but off at the chainstay junction again it is probably the frame at fault. If nothing rubs it does not really matter. Many cheaper frames are like this.
