since I can't read the original german, was the test down over various yaw angles? or only at yaw angle 0?

0 and 10 degrees. With and without rider. For the comparison they used the results without rider since the error was too imense with rider.

Sounds like they need to work on their test protocol ;-)

well, if they were truly 'independent', they'd have procured the bikes on their own and tested them. I'm fully aware of the economic constraints faced by a magazine in the bike industry, but that's the reality. If they're accepting product from manufacturers to test, that calls into question their objectivity right there.

It shouldn't have been that hard to get these bikes from a shop, either on loan or purchased at a price that would have allowed them to test the bike and re-sell it at little/no cost.

What have 'we' deduced from the bike+rider interaction?...how does it affect the air+bike?

it will be just as fast/aero as the next!

I saw take this studies and try not to worry about them that much, find the bike that fits and fits what you want it to do and it will be just as fast/aero as the next! To many people have got caught up in this aero thing from all of these companies, let it go, all the bikes on the market are good bikes!

Tour magazine of Germany tested the who is who of the tri bikes in their last issue. This magazine is considered to be the one which tests in the most professional manner of any bike magazine in Europe (maybe even the world?). So their plan was to end all the speculation about the most aerodynamic bike and just find it out by themselves. That would’ve been one of the first in depth tests of top end triathlon bikes by an independent source ever.

Surprisingly Cervélo and Specialized called back their bikes. That’s very sad and makes me – and many others, I’m sure - think that they are afraid of not being as good as they proclaim (especially Cervélo with their P4). Maybe Gerard could explain why they withdraw their bike? Hopefully there is a logical reason behind it. At least many triathlon enthusiasts in Germany/Austria/Switzerland would be relieved if he could give us a good reason for not participating.

Scott won the comparison with their Plasma 2 – so they try to advertise with it and show excerpts of the test on their website:

The top 3 in the overall ranking were:

Scott Plasma 2
Kuota Kueen-K
Cannondale Slice

... I'd rather have NO data rather than BAD data...

Actually that's the conclusion of the tour test! They state that the differences between those aero frames are marginal whereas the gap between standard road frame and aero frame is recognizable! The outcome was: No need to spend thousands of dollars for a high end triathlon bike. Get a cheap tri bike and work on your position!
