CD's Saturday cycling tip: meet Sheldon Brown's website

As some of you know, I've been spending time lately in the forums of U.K.-based cycling magazine Cycling Plus. While there I keep seeing references to Sheldon Brown and his website. So, cycledork asked, who is this Brown dude? It turns out Brown is a Massachusetts resident (I love going overseas to learn about domestic resources) with many interests, including bicycles. Looking it over gives me comfort that cycledork won't have to reinvent these wheels. The site's many offerings range from a glossary to a gear calculator that tells everything from gear inches to speed in a selected at a selected cadence. Very dorkish and thus very cool.
