Frank, I don't really care what the study says, but Macca was 2nd at Kona, Tom Evans 2nd at IMLP, Courtney Ogden 2nd at IMC...all PC users. Brian Keast started winning his age group at Kona after starting to use PC's. Coincidence...perhaps. Its probably a coincidence that Fabian Cancellara and Dave Zabriskie were 1-2 at Worlds ITT on Cervelos. After all, Cervelos can't possibly make you faster...its all placebo effect :-). Like I said, these studies can say all kind of things...what I care about is how the athletes using the technology do in real racing.

If we all waited for definitive proof from studies there would be no innovation. No QR Superform, no long sleeve tri specific wetsuits, no fast clinchers, no aero helmets, and Greg Lemond would never have one the 1989 TdF using those unproven "weird" triathlon bars (aka aerobars)...someone has to take a leap of faith and try something new...hey, without that, we would not have slowtwitch and we would not have the ironman (coincidentally, Frank Day was one of the original finishers, who took that leap and decided that it might be possible to do all these three sports in those distances in one day).

Bottom line, is that there are innovators and early adopters of technology and then there are guys who will wait until something is proven definitively. Everyone can have their own approach to adopting tools and technology. I suspect that most of the guys wanting studies to prove things definitely have never worked in a startup either :-)
