I'll save you the trouble...
My team and I ordered 6, we're 5 for 6 with the modded fuji chainstays (crimped at the factory to accept larger chainrings / a standard track bb)
I'm currently running a 103 spindle on my Dura Ace 7710s x 50t ring. No rub, about 2-3mm to spare. Size 52 cm.
One rider ordered a 61cm, and was sent the older non-modified version and has had to run the recommended stock FSA crabon crankset with a 110 bb spindle.
