Looks pretty good.
However.
Looking at the mechanical group, the way bigger RD undoubtably shifts fine. But for a tri race bike with double chainrings and, say, an 11-25 cassette, I kinda prefer a small more compact RD (like currently avail with Ultegra 6800).
Is it this end of small compact RDs? If yes, this is a non-trivial negative for race bikes.
