Help with front wheel off and on, Trek 820
I have a Trek 820 bike. I don't often take the front wheel off but every time I have it's a giant production, and I wondered if anyone had any helpful advice.
The front tire has a gizmo like this picture ( http://galleryimage.naver.com/1/2004.../36m1721m0.jpg
) to attach it to the frame. My issue is that every time I put the wheel back on, one side of the wheel rubs on one of the brake pads. The first time it happened I thought there was an issue with the brake, that it got knocked around or something. But it ended up being that the front tire wasn't quite centered. Is there a way to fine tune/adjust that? I just got pretty frustrated dinking around with it this afternoon and couldn't get it right. The brakes at the handle bars can't be loosened anymore (and I don't really want them unsafely loose).
Any help would be appreciated! I'm sure it's not supposed to be this difficult, but it sure seems to be for me.
