Yann, do you think it would the same size for a 56 frame?Unlikely, the height from the top of the rear wheel to the the seat clamp is going to be greater.
Take a piece of cardboard or manila folder and place it against the side of the trailing edge of the bike, trace the contour (blue lines as shown on the attached image), then place a ruler on the sketch and as accurately as you can, draw a 3 inch line next to it, I can use that for reference. Scan the drawing and post it in your response to me.
