So I've been noticing the birds are starting to prepare for migration, which reminds me that winter will be here sooner than you think. And I want to be prepared (I used to be a girl scout), considering that I plan on riding during the winter and haven't done so in Chicago before. I've read in a couple of places that single-speed is the way to go for winter. Currently I ride an old Schwinn 10-speed road bike that I've been considering converting to single-speed for a little while now, since I never change gears because I never feel the need to. But my friend who rides fixed-gear said I should hold onto my gears because I'm going to need them when it gets windy. So what are folks' opinions? Single-speed or 10-speed for our blustery, gross Chicago winters?
