I'm going to try doing a single-speed conversion on my trusty Long Haul Trucker. I didn't get too much component damage last winter, but I found the maintenance effort draining. Plus my time for that is limited with a new addition to the family.
Another thing I want to try is leaving some brushes in the (outdoor, covered) bike parking area. I had a decent amount of rust in the chainstay bridge area last year. I'm hoping that brushing off the salty road snow/slush on arrival will help avoid that.
