So, I ran across this drag chart for Boyd on their website:
And found this published on Zipp's website:
To me, this looks like that the 808 has a few grams less drag at <5 degrees, and then the 90 mm Boyd has progressively less drag as yaw increases. And the Boyd has negative drag after 12.5 degrees!?
Of course, Boyd is American made, etc. No Chinese carbon, that I'm aware of. (Edit: Boyd rims are sourced in Taiwan. However, they are assembled in South Carolina. And Boyd has been making wheels for years. I'm not aware of product problem.) A set of 90 mm Boyds is $1500. About half of the MSRP for a set of 808s ($2975).
Didn't bring up the ENVE 8.9 (which is more than the Zipps, I think) because I couldn't find a drag chart that used grams of drag as a metric. Presumably, they'd be comparable to the 808 performance based on information on the ENVE website.
Btw, I get that there are scientific problems not having these in the same test w/ the same controls, etc. I believe it's reasonable to deduce, though, that their performance is comparable.
So, back to the original question. Why pay double for Zipps or ENVEs?
