I was off work for two weeks during the holidays, and only got in two rides during that whole time. I was a bit worried about losing leg strength for the daily commute, but my fears were largely unfounded. Traffic volume was very low this morning, as many people won't be back at work until next week. The new wheelset is awesome. It's heavier than the Open Pro/Hope Pro II setup, but the studded tires fit much better, and I can run higher pressures than before. I can also switch wheels out in 2 minutes, meaning that I don't have to change tires when it snows. Sweet!
