Many thanks to our friends at Fiets.nl for sharing these pictures of a prototype Shimano Dura Ace 11 speed groupset, seen at last Sunday’s Kuurne-Brussels-Kuurne on Alex Dowsett’s Pinarello Dogma.
Fiets.nl report that Dowsett’s Dogma was the only machine dressed in the mechanical 11-speed set-up, actuated by a roughly finished rear mech. Other prototype kit adorning Dowsett’s machine included the brake calipers and levers seen below.

The roughly finished rear mech: mechanical, not electronic
