Perhaps not a sister board, but maybe just a thread.
Here are a few for starters:
1. Does anyone have a link to the Velonews article that did a wind tunnel comparison of different wheels? I can't remember where I saw the reference to it.
2. Does anyone know how to translate grams of drag into watts of power? The Hed website has an interesting wheel comparison graph (
http://www.hedcycling.com/aerodynamics.asp), but i don't know how to translate the differences to real-world performance. The graph, for example, claims that there's an 80 gram difference at 10 degrees of yaw between a Stinger Disc and Zipp Sub-9. Taking this at face value and assuming no wind and a constant 300 watts, what would difference (if any) would this have on speed?
3. Just how much difference is there in aerodynamics of different discs or 90mm section rims? There is substantial variation in the weights- in discs, for example the Hed Stinger disc is a claimed 1,130g, Zipps are around 1,000g and carbonsports claim that one version of thier discs only weighs 780g. Are aero differences between brands substantial enough to offset a 200g weight advantage on the slight rises and accelerations of a typical TT course?
4. Has anyone had a session in the wind tunnel with Drag2Zero?
