Have a frame I think is perfect for me in my Boreas Ignis and it may be ally- but rides well. Had to make couple of compromises on set up though due to my short thighs. Saddle as far forward as possible and Short reach bars. If I were to have money no object it would be the same frame but with a 74.5 degree seat post angle. Just as I have aquired in the Pinnarello UNO today. Top tube is just a fraction shorter than my usual 535mm and it seems to fit out of the box with no changes of anything. Groupset and I can't see me needing anything better than Ultegra but I suppose Dure Ace would work more efficiently.Components and they would be about as light as I can go without compromising strength but it is the wheels where I would get my dream machine working. Want them as light as possible and I want rigidity and still keep my teeth in place. Something like the handbuilts I already have but 300grammes lighter please. Dure Ace carbon perhaps.
