Nope, not a clue. Since the circumference of a circle is pi times the diameter, why don't you wrap a strip of paper around the seatpost, measure the length and divide by pi (3.14159)? Round the result to the nearest clamp size. The bottom bracket spindle length is dependent on the cranks you use, and if Campy, on the seatpost diameter. Branford Bike will probably have appropriate recommendations in its section on bottom brackets.
