What do I need to commute in snow? Assuming on streets with 2 feet of snow and not plowed. I just found out that my Ritchey Speed Max (fine treads in the center but knobies on the side) does not give me any traction. I do have my stock Specialized Enduro tires. They are about 2.3 inches wide and close to 2lb each. Would clipless pedals be a problem such as the cleats cloated with snow and ice can can't clip in? I seriously don't want to spend a lot of money on my commuter.
