Page 17. 7.4 watts of drag saved over previous generation Squoval (read: old R5) frame, which wasn't the most aero frame around.
Here, Scott lists CdA, which is the coefficient of drag (related to shape only) multiplied by frontal area. At 12 m/s(43.2 km/h), Foil creates around 4 watts more drag than the Cervelo S5 (76 watts for Cervelo and 80 watts for Foil, excluding rider)
From the other standpoint, stiffness, http://velonews.competitor.com/2011/08/ ... eam-issue-
Scott Foil is listed stiffer than the Ridley Noah and the old Felt AR1. The test is 3 years old though, and only Foil and Noah were not updated until today.
So, aero and stiff. A viable alternative in my book.
I have nothing to back up that the Aeroad is stiff but I'd have thought the Aeroad was built to be stiff.
I would more than like to see other test results, and eat my words if those contradict what I say.
Sorry for the hijack.
