Cold but fun. Second day commuting on my new bike. Ran the tires at a higher PSI today so I gained a little speed, as long as I wasn't fighting a headwind. Was just under 20 on my ride home, with strong winds making it feel more like 8-12. Coldest night so far this winter. The ride to work was great weather at least.
One thing I've noticed going from mountain bike handle bars to taped road bike handle bars is that my headlight stays in place much better. It's nice.
