Our low temperature is supposed to drop to the low teens on Thursday morning with a wind chill around zero. I haven't decided yet whether to ride to work. My coldest commute so far was about 15 F, so I could possibly set a new record by riding that morning, but the forecasted wind chill is making me think twice. I am most concerned about keeping my hands and feet warm, as they have been borderline uncomfortable on other days that I rode in the teens. I am also concerned about the admittedly slight risk of having to fix a flat in temperatures that cold. Although I seldom get flats, they seem to occur at the most inopportune times.
