Look closer, it's there. Should be announced fairly soon, and I'd imagine it will show up at Le Tour in a few weeks time. They actually had accidentally posted the manual online a few months back, but it's since been removed.
I don't doubt the claims about the manual and any announcements,or that a Speedmax disc is coming...but I don't see how you can definitively say in that vid that it is a disc bike from the split second head on shot at 0:45. As much as I want to see a rotor, I see little dark spots at the fork crown which could be hidden brake pads. What am I missing?
