Excellent Shimano Product
High quality, precise shifting with no fuss; as expected from the Dura Ace line. Quite expensive, however, well worth the extra over and above the Ultra offering. The weight saving is a bonus when compared to the mechanical groupset, especially when combined with the internal battery.

Very similar to Ultegra
Brilliant shift from these, I also have the Ultegra version and it's just as good. This one a bit lighter and says Dura Ace on it though.

Bought for upgrading my Scott Plasma 3 TT 10 11 speed and basically it just works. Bought to replace the previous Dura-Ace 10 speed version. Not much I can say really
