So I am trying to figure what spindle length I would need for my bottom bracket. I know it is not an easy task and generally manufacturers should be contacted. However Sugino is in Japan and their english is not great and T.A. Specialties is in France and hasn't gotten back to me yet and I would be making a custom crank anyway with a tripelizer.

As some of you know I am going with Co-Motion Cascadia in a 56cm. I plan on using a Phil Wood BB but I am unsure of cranks right now. It is either going to be XD600 or even better a "cobble together" from T.A. (Zephyr cranks, outer ring and middle adaptor/triplizer and Zelito inner ring). I know according to the late great Sheldon Brown that XD600s are about a 113-118mm and double Zephyrs would be 110mm (though the info could be old) and he lists old T.A. Cyclotourist road triples at about 120-123.5mm.

I am hoping someone might have some better insight here because I am not sure exactly what to do aside from buying stuff and hoping it works. I know it is best to have everything and measure together but I am trying to get parts now and get everything ready for when I finally get the frame. Plus the Phil hubs and BB are somewhat of a package deal that I am working out with a former colleague of mine at the shop he manages.
