I'm a bit confused by Canyon. When I spec'd the Rose I wanted to also consider them against it, but I couldn't get the Endurance with Disc brakes & Di2. Therefore Rose were never even challenged.
However I knew that in 2016 Canyon would catch up, but looking at their '16 bikes I still can't see one with Disc Brakes and Di2. Very strange.
At Eurobike, Canyon are showing an Ultimate with both, but unfortunately it is a prototype only.
