I bought a new Cannondale CAAD9 5 and had to try it out. Friday around here was nice, just a little windy, but coming home from work on Sat. night, it was my first ride in cold weather. It was 9c or 48F. I had on leg warmers, and a cheap rain/windbreaker, and full gloves, and all was fine. I thought for sure I would be cold by the time I got home, but nope, very comfortable.
