Is this a common problem?
Let me explain further.
Our youngest's bike often suffers rubbing front brake discs after wheel removal and replacement. Last night I finally (after lots of head scratching) figured out why. With the bike upside down (yes, I know I know, shoot me :mrgreen:) and the front wheel in the fork drop-outs, the wheel can be moved a tiny amount fore and aft on each side, and will stay that way upon tightening the QR.
Now, if one side is forward, and the other side back, it's enough to cause disc rub on a front brake that was previously working perfectly with adequate pad clearance.
So obviously an oversize drop-out spec, but having no other disc braked bikes on hand, just wondered how common this was?
