Spindle Length Question
I am putting a new Sugino XD500 triple crank and new cartridge-type BB on a '83 Miyata 610. The old "cup and cone" BB spindle I removed seems long----124 mm (excluding the threaded ends). I think it was original, but can't be sure. The bike was a CL find, and I rode it very little before stripping it down.
Question: What length BB spindle seems right in this case? What will give me the optimal chain line? I am putting a new 7-speed Shimano freewheel on the original hub. The spacing between the rear DO's is 126 mm.
THANKS!

To me, 124mm sounds right for a vintage touring bike set up with a vintage triple. Your new crankset, however, might work with something shorter. Does Sugino offer any recommendations?
