Home About
Jobst Brandt, who posted most of these articles, is the author of the book The Bicycle Wheel. Another selection of his articles can be found at the Frequently Asked Questions section of Sheldon Brown's website. The selection here differs in character in that it has infrequently as well as frequently addressed topics. It also goes more deeply into arguments; there is no shying away here from technical detail, nor from controversy. The FAQ is thus probably a better read for those new to the workings of bicycles; the articles here are more of an advanced course in the subject (although none of this stuff is horribly esoteric).
