I had a 785 Huez RS and loved it. I built the frame up with EPS 11 speed Super Record and Bora 45s. Great climbing bike, as dinosaur said, the headtube is quite high, I rode an L and am 6'2. Only sold recently as I wanted to build a disc frame up instead.
I've seen a 785 Huez new for 1200 euros... how are they to ride? I'll build it up with 8070 di2 and some chinese wheels I have kicking around
