Back in the day when I rode my singles, I rode my CF bike all winter. Perfect bike for that. Doesn't corrode, stronger, smoother. I used winter wheels with inexpensive rims and just re-rimmed them when they wore through. Every bike should have at least 2 wheelsets anyway. Now we ride the steel CoMo all winter with nice rims and just spend a tiny bit more replacing them. It's holding up fine, but we don't salt our roads here. The only thing different about winter riding really is that you need nice hubs with sealed bearings including in the freehub.
