I had been commuting on my New Tarmac, but this will work better/be more practical during the cold/wet season. By the way, thanks to the inspiration of this forum and all of you guys I have ridden to work and back (22miles daily) since April and don't intend to stop. This, in addition to my regular "road bike group rides", puts me near 200 miles per week on a bike. Also it puts me at 200 pounds instead of 245 like I was back in April.
