I got a trek domane project 1 with dura-ace di2, i put hed ardennes plus 25mm wide rims on it, the thing is a rocket, stiffer in the bottom end than a madone but way more comfortable to ride.I was coming down lake mountain and it 70kph, i could have gone faster but the organic component failed (me).It is light fast and comfortable, i couldnt wish for anything more ( dont ask how much it cost)
