Fixed/ Single-speed bike book? Hello. Does anyone know off a book, or even Website, that explains how to build a fixed/single-speed bike from scratch? Are any of the general books any good; The Bike Book http://www.amazon.co.uk/gp/product/1844254216/ref=reg_hu-wl_mrai-recs, or The Complete Do-it-yourself Bike Book: Everything You Need to Know to Fix, Maintain and Get the Most Out of Your Bike http://www.amazon.co.uk/Complete-Do...TF8&coliid=I2BLPYQ84W8XQ9&colid=2U736MJV85579. Thanks.
