And... I'm done.

There are some older graphs around, but putting in data from older versions of current bikes is problematic - Felt talk about this in their white paper, ie which version of a DA is being compared?

good info, appreciate the effort to post them all up. However you will see who has less drag etc, just by the source you labelled. Eg, can you imagine Specialized posting something in which shows a cervelo having less drag than a shiv?

Pinteresting.

To be sure. However, comparing, let's say, a DA vs a Plasma using Cervelo's data might be useful.

Dunno if I am supposed to hotlink the photos here, since the screencaps are obviously from the tour magazine ipad app, but heres a link to their 2012 tt frame test.

I wonder what competitor bike is A (in light blue) - indistinguishable in performance from the SC?

Competitor A, the one in light blue, is the 7 series Speed Concept.

You sure? In one of the graphs further up the page the 'TCT' SC is compared to the 'OCLV' SC. I believe this is the 7 vs 9 comparison.

If you are correct then no-one would buy a 9 series, and also none of the 7->9 improvements give any aero benefits which hardly seems likely.

I'm pretty dang sure. They use that graph on the promotional posters they give to shops, and I saw it everyday haha. But, I double checked the white paper and saw what you meant. Its interesting that between your posted graph and the one in the white paper, the slopes of the line match up. However, in the white paper, the 9 series at 0 degrees has 550 grams of drag where as in your graph, its closer to 600 grams of drag.
