be prepared for flats, meaning with new tires or new size tires you might need a cpl new tubes in matching size to keep in your bag. patch kit fresh? the winter I commuted, I started by keeping my bike outside & would spritz it off w my water bottle when I got to the office or at home (refilled w warm water at destination). heated loading dock at work, no problems drip drying on sheets of cardboard. at home one cable froze up outside. so I decided to bring it inside every night, down the stairs thru my bulkhead into my (mostly) unheated basement which stays 50 degrees, well above freezing. put down cardboard so it could dry off. keeping it clean & above freezing overnight helps a great deal. keep some paper towels nearby too
