What do you mean we will see them, they're here!!! I think the top tier bikes are all pretty much going the way of electric and hydro, if you can't at least acknowledge the obvious it just becomes a matter for yer bud, Ned Ludd. You go to Interbike, what are you seeing, people still braking with their feet?
I don't know one person in the industry over 50 that is pro disk brake so you're not breaking any new ground here, but I still believe that this relatively old tech now infiltrating the road/cx range actually has the ability to get better, much, much better.
Of course they won't, and the biggest reason for the Euros is weight, not performance. KY was one race and epic conditions, even the rim brakers had almost no brakes. Ask any of the American pros that were running disk for most if not all of last year, they all loved them. O' brother Busted, that tubeless analogy is so off! Ha-ha!!
Every manufacturer of note has a drop bar bike with d-brakes, not even in the same ballpark.
You just described my Ibis Hakkalugi!!, and dozens of other bikes like this on the market. You know, I bought this thing because last year I saw one being built up at YOUR SHOP!!!!


Although, now that I think about it, it was in Jim's stand.
