Knowing that there are two hemispheres, I'm asking folks to show us the bike you ride in the winter (regardless of when that is for you). Mine is one made from a Nashbar commuter frame and parts left over from other projects. The thing that makes it my winter ride is the fenders, bar end shifters (much easier to use when wearing "lobster" gloves), and studded Nokkian tires.
Oh, and I realize those in warm weather are likely to post rides that don't require equipment able to deal with snow, ice, rain, etc. But that's OK. Post them anyway.
