I watched the live broadcast and he definitely had a PCV on his bars. I didn't get a close look at his cranks though. Other riders were also using SRMs (or at least the computers) but weren't part of the live data broadcast.
Uhh, yes. Which is partly why I'm willing to bet he wasn't paying too much attention to his SRM. He was probably paying much more attention to RPE - and to the nagging realization that he was about to get his @ss kicked out of the the race.
