Welcome! My name is Carl, and this is my blog. I am both a bike geek and a math nerd, but these days I'm more the former than the latter. Most of the time I'll be talking about my adventures from the cockpit of a singlespeed 29er mountain bike, hence the title. Occasionally I'll delve into the rest of my life, but since my life essentially revolves around cycling, well, you do the math.
