Hi! I'm new to these forums (just introduced myself) and am interested in winter commuting. I just moved from Phoenix, so my bike and I are unaccustomed to winter/snow. I only work about 2 miles from my apartment and that would probably be my longest/most regular commute (I'm like 5-10 minutes from whatever stores I need to go to, so work is the farthest away). I have a very basic mountain bike--this is the bike I have: http://phoenix.craigslist.org/evl/bik/804366733.html
What I'm wondering is what are the BARE MINIMUM things I should have for winter cycling. Our winters aren't terrible here, I hear, so I'm hoping that's true. I'm more interested in gear for my bike than clothing since I have a lot of layer-able stuff already. I'll be traveling on fairly maintained roads w/ bike lanes that will likely be plowed all winter.
Any suggestions are much appreciated
