I'm trying to find that grad student study. Tons of data, showed zero disadvantage, advantage ranging from 0% (non-fit riders0 to 5-6% for very fit riders. This was on Rotor rings, not BioPace.
What was interesting to me was she was a cyclist and set out to prove there was NO advantage to the Rotor rings. She ended up moving to Europe and was employed by Rotor to convince teams to use those rings. No idea how that came out, as it was a few years ago.
Again, my TT buddy uses both Rotor and Absolute Black (but in red) and swears by them. He is very limited in endurance (bodybuilder), so he wants to very fast, for as short as possible, and he really is pretty fast over about 10 miles.
