Nothing to do will 11 speed at all. I was a Dura Ace rider but I can honestly promise you it does not even come close to Campag. Shimano wears out and Campag wears in.jitters said:Yes, Campy is so much better, because it has 11 speeds.
Their impression? Shifting is amazing. Ergonomics/buttons a bit dorky. I'm not going to run out and buy it but I'd love to try it.But while the mechanical drivetrain is just as capable of knocking off similarly smooth shifts under ideal conditions, Di2 makes nearly every shift so dead-on perfect that it's almost eerie. Instead of forcing the chain on to larger cogs or rings at less-than-ideal times as we often do with mechanical shifting, Di2 basically only shifts at the designated gate and it seems to hit its mark almost every time.
