If I remember things correctly, Fabio Saachi has it on his bike as part of a Campag test programme. It's carboned up to the eyeballs so much that it's lighter than Record, even though it includes a battery.
I wonder if this system is quick, especially on the front derailleur with motor instead of solenoids. Perhaps it doesn't have to be that quick, when I think about it my FD sometimes changes everything but instantly and I survive anyway.
