Appears to be bike only data..."rider-on" data please. Also, we need to see how each bike was set up equipment-wise. Same as always...

edit: Found the white paper here: https://www.cannondale.com/...emSix_Whitepaper.pdf

Apparently, that drag plot is values normalized to a SuperSix with the same KNOT64 wheels. In other words, it's a difference plot, not absolute values.


DGR: It's just typical LSWT output. The "normalized" comment reflects that the output is normalized to a standard day: 30.0 mph, etc. as usual.

There's bike build detail list (no pics though) in an appendix. Some interesting wheel depth (e.g. Aeolus 5 on the Madone) and tire width selections in there IMHO...


DGR: All as delivered. I agree, a product manager who knew and cared about performance could have made some different spec choices.

Hmmm...a yaw-weighted look at an overall value. Interesting...Now, if only someone would combine that with rolling resistance values to determine an overall system value ;-)


DGR: Hm, do we know someone who might have already done that?
Actually, we included Crr, etc. in the calculations and system performance is reflected in the scenarios in the white paper (climbing, descending, sprinting, etc.)

Nice to have your comments Tom.
