Timed my short commute today on my new fixed-gear Redline 925, and it's about 10 minutes door to door, which gives me a nice 40 minutes at home for lunch! It's a little less than 2 miles each way, so a nice easy 7-8 miles each day before I even hit the gym at night certainly doesn't hurt things, and I love it!
Only my second week of commuting. Fenders, headlight, more blinkies coming for Xmas.
