Jacek, the tube sizes are the same as the Corsa 01 except for the seatstays. Top tube and seat tube are both 29mm diameter, down tube 32mm. The ASLK has seatstays that are 14.2mm diameter at the top versus 16.2mm on a Corsa 01. Chainstays are the same between both. The lugs are all different to the Corsa 01. The fork has the Columbus spiral rifling in the bottom of the steerer. The tubes of the main frame don't have anything visible through the bb area, I specifically looked after discovering that the fork was Columbus.
Some detective work was needed on the steerer label, needed an ultraviolet light and a magnifying glass.
