I'm managing to stay pretty warm on my 45-minute commute, but my biggest fear is getting a flat and not being able to change it because my hands and the tires are too frozen and unpliable. How do you deal with flats in sub-30 degree weather? I currently run size 35 Performance clinchers (with Kevlar belt). They've been surprisingly reliable, considering the price I paid for them.
I tried searching the forum for something on this but had no luck.
