The aim of this page is to be a repository for information I’ve found regarding Bicycle Aerodynamics. It’s going to take a while to get everything loaded up and to write a primer & glossary but the grand plan is in motion…
For starters, over the years I have compiled a list of measurements of key frame tubing dimensions from TT/Tri bikes. In the early days of TT/Tri bikes aerodynamics were fairly simple – narrower was better. Now we are in the time of managed airflows rather than just making the smallest hole in the wind possible. However – skinny and deep tubes are still a pretty good indicator that the designer was on the right track.

Articles I’ve written pertaining to Aerodynamics.
White paper released by (now defunct) Lew Wheels in ~2009 that I saved before it disappeared from the web. Lew Disc Testing
Specialized tested their Transition against the P3 in 2008 and (being Specialized) created a slick marketing presentation. Some useful information about the basics of bike aerodynamics.
Trek White Paper from 2007 comparing the Equinox TTX, Cervelo P3, Scott Plasma 1 and a Madone road bike.
And plenty more to come. When I have time. No, I don’t know how long that piece of string is…
