    TT equipment wind tunnel testing results article.

    Here's some data about gains made possible on your TT times.

    Sounds like some pretty careful tests. Puts some numbers to the theorys.

    except it confirmed mostly the obvious - full aero is faster than non-aero. It would be nice if someone tested various TT frames for aero properties, especially since there are so many contradictory claims out there - whether a deep, tight rear wheel fairing is better (Cervelo) or worse (Look), how much difference front ends make (Oval Jetstream claims 55 seconds/40km for their design)...

    Still fascinating that I could drop over 5min in a 40km TT. I might have to borrow a TT bike for nationals, assuming they don't ban them.

    I found it interesting to compare the numbers for what they did test. Sure, there are thousands of possible combinations of equipment, but they tested using some pretty standard stuff, and gave their 'gross' findings. Instructive to see the relative importance of the various elements of a TT set-up in actual watts of power and miles per hour..

    Yeah, it would be neat to see various equipment manufacturer's stuff put to the test, to see if what they claim is really true..but it'll never be done...

    look through the archives from the "wattage" google group using powermeters some of them have methods for at least accurately comparing different equipment

    I don't have the patience for that but I do like to read what other people find

    except it would have been more interesting if they had actually used an aero tt bike. I assume most people here are aware of the epic failures of the specy transition...
