Sheldon Brown died.
Sheldon was a man who rode bicycles. A lot. And thought. A lot. And decided to share what he knew. On an epic scale - with no renumeration but your satisfied curiosity.
I'm not sure how one can possibly measure the number of people Sheldon was a virtual mentor for - nor the number of people who were encouraged to fix a bike, get on it, and in so doing, slowly begin to realize a vision of what our world could be - how we could live healthier, less wasteful, more aware and creative lives. I like to think the here and now is enough - that one must not need to be purchasing something in preparation for, jetting off, driving toward elsewhere to live. And if Sheldon stood for anything, it was the counter principal; build, ride, live, right now. And that seems to be something that people realize.
I'm currently working on a Pugeot fixed gear, frame found on the side of the road. It may be a gift bike, or a loaner for anyone who visits. Her name is Sheldon.
