Rode my first single-speed commute today. I converted my regular commuter bike to a SS/fixe last week, and I'm still getting the hang of it. Decided not to risk death by riding it fixed, but wanted to see how the hills worked out with one gear so rode SS. It was surprisingly easy on the uphills, but frustrating on the downhills. With my freewheel gearing (42x18), I spin out about 21 mph, so I pretty much coasted down all of the hills. Several hills on my route I can easily top 30 mph coasting, so that's why I rode SS rather than fixed. I've only rode fixed once so far, and don't trust my skills for riding in traffic yet.

Weatherwise, it's a good day for riding SS. It snowed last night, but it was just a dusting and the roads were clear. The temperature is supposed to get no higher than the mid-30s, so I don't have to worry about changing my clothes for the ride home. Plus my legs were fresh after driving yesterday due to rain.
