Sky trialling Dura-Ace 11-speed at Giro

Sky’s Ian Stannard has been using a Pinarello Dogma 2 team bike equipped with a prototype of Shimano’s new Dura-Ace 11-speed components during the 2012 Giro d’Italia.

The new mechanical groupset has had a radical redesign over the current Dura-Ace line. Aside from the extra cassette sprocket, the most immediately noticeable external change is the sleek four-arm crankset.

The brakes have also had an overhaul, and the calipers now feature an extra pivot.

Official details on the new group have been thin on the ground, but given the ‘finished’ look of Stannard’s components we can assume that they must be nearly ready to release to consumers.
