seem to have rather "endurance" set up because, I still think, they have turned the tour into a serial sprint relay where power is more important than being aero.
I've read that it's not unusual for riders to drop their saddle height 10+ mm during the course of a Grand Tour as the fatigue sets in. It's not that surprising that they favour a more "endurance" fit considering the event. Obviously their TT stage positions will be completely different.
