-Repack your bottom bracket, headset, and hubs in the fall.
-Lube your cables weekly, after lubing, dab a glob of grease at each cable housing end.
-Dont forget to lube your gear shifters and brake levers.
-Lightly spray lube on the outside of your derailers, hubs, bottom bracket, seat post, quick release levers and any other exposed metal before each ride.
I'd add to that if you use clipless, relube the cleats. I'm currently trying to get my cleats off my old shoes so i can put them on my new lake boots.
