From Bike Radar:
Though Shimano's new Dura-Ace Di2 system still isn't ubiquitous in the peloton on the road stages, nearly the entirety of the Rabobank, Garmin-Slipstream and Columbia-High Road TT fleets were so equipped. Speedy shifting, ultra-short button throws and fancy auto-trimming front derailleur aside, Di2's biggest draw here was perhaps the multiple sets of shift buttons - one pair out on the aero extensions as usual but another neatly integrated into the brake levers mounts on the base bar.
