Must be the angle of the photo. It is the exact same frameset. I've got spare parts from dolan that actually have a stamp with "1056" inside.
I wondered about the angle.
So the only difference would appear to be that Dolan is still using a pressfit bottom bracket and Carbonda has moved on to BB86. I'll speculate that Dolan either will do, or has done and hasn't updated the photos on their site.
Nice to know one can get 1056 spares from another source.
