I've got a odd wheel problem that I can't diagnose. The bike is a '06 Fisher Hybrid, running on weinmann wheels (I forget what the hubs are). The problem is that when peddling I noticed that the rear wheel is pulling to the left. On hills I'll actually pull the rear tire into the frame.
I've checked the following:
* No broken spokes (had one a few months ago, but I've since replaced it)
* Hub is not loose
* Reset wheel to make sure it was seated correctly.
Any ideas what could cause this? I've searched the forums and found cases where people had this as a result of improper seating of the wheel, or loose hubs, but both of those appear fine in this case.
