It's getting chilly here in Chicago. This morning was wet & cold: about -8c. When I got to the office I found the seat post had frozen into the frame and needed a lot of effort to remove it. I really think the Xootr frame QRs are on the wrong side: they should be on the leading edge away from the muck. If I get around to it I'll knock up some kind of cover using neoprene or something. Until I do, I guess I just have to live with road muck in the seat post and an occasional frozen post (or buy a fender / mud guard...).
I've also noticed that drivers are even less attentive to bikers. I was 'nearly doored' three times yesterday on the way home - that's a record.
