I've been building bikes for a bit now and doing what I can to document the process in between the sheer joy of building and learning stuff. I thought I'd share with the Make crowd what I'm learning and how. I'm starting from only the most basic bike fixing knowledge and building from bits and bobs, learning about different standards, (did you know there are four kinds of bottom bracket thread? I did not!), different geometries, how to build wheels, and so on.
