Damon Rinard pages edited, updated, reformatted

Damon Rinard, who now works for Cannondale, had to turn his Web pages about bicycling over to Sheldon Brown back in 2001 when hired by an earlier employer. Rinard’s pages contain a wealth of information on bicycle design, and the renowned Spocalc bicycle spoke length calculator. Rinard even describes how to build a carbon fiber bicycle frame at home, and it’s easier than working with steel. His pages on improving aerodynamics are a real eye-opener. We have improved the translations of several articles originally written in German, checked links and reformatted the pages to make them easier to read in a modern browser.

Air bag helmet demo

An air bag bicycle helmet has been in the news lately, and there is an evaluation of it online, if you care for the details. However, years ago, Sheldon posted a scan of a poster for another air bag helmet on the site. Unfortunately, he had only a rather worn copy to scan from. We’ve now had the loan of a copy in fine condition and had it professionally scanned. A small copy of it is below but you may view it in its full glory elsewhere on the site.
