Was curious. Anyone know if Colnago has stated a standard rotor size spec for c64. Mine was built 160/140. Interested to know if Colnago has taken a stand. Related question what is the UCI standard for neutal support. I heard but can't seem to confirm its also 160/140

The disc size is related to the calipers, not the frame. With Shimano, I believe you use an adapter for 160mm rear rotors. For Campy, you have to purchase either the 140mm caliper or the 160mm caliper, they are not interchangeable.
