I commuted into work today (4th time I think) and shortly after I got in, it started to precipitate freezing rain! I quickly ran out and put my seat back in so that the rain/ice would not travel down to the bottom bracket.

Besides the possiblity of slick roads and brakes, is there anything else I should be careful about (chain, derailers, bearings) when I leave work today? What should I do once I get home besides wiping down the frame?

Although it would be heavier than normal, it would be one slick bicycle! Since it is steel bike, I'll make sure to not lick the ice.
