I agree fully. Everything else you said I'm going to pretend you didn't.

Has anyone ever had their bike just feel "different" all of a sudden. The last couple of days my bike feels really "squirmy" or something. It feels like something in the front end... like it just doesn't want to track straight or something. At first I thought maybe I was low on air in the front tire, but it seems fine. Headset seems fine. Bars/stem are tight. No idea. Maybe it's because I did some riding on my road bike on the weekend and now my fixie feels weird..? I have no idea. It's weirding me out though.
