Bicycles

Kevin Kelley's Cool Tools is a handy site.

A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. I am chiefly interested in stuff that is extraordinary, better than similar products, little-known, and reliably useful for an individual or small group.

One of the recent tolls Kevin highlighted is Sheldon Brown's Bicycle Technical Info. If you are looking for info on bicycles, this site has all the info you could ever want - a giant glossary, bits of cycling history and plenty of specific instructions and photos. It's a site worth bookmarking.
