help with dura-ace FC-7410 cranks/bb fit

so i have come upon a set of these cranks. they are stunning, splendid, the bees knees, and all that. the problem, however, is i understand they require a 103mm bb. since i cant find that length in shimano, i am looking at either the sugino or the fsa:
will both of these work without problems? and how will this affect my chainline? would i need a different front derailleur?
please advise...

Sure, the Sugino or FSA will work fine. I have an ActionTec ti BB in that length and it's worked fine for over 10-years (get the SKF bearings). Chainline should be perfect with 103mm spindle since that's what the crank was designed for. FD doesn't care what BB or crank you have, only the placement & size of the chainrings. As long as you get the chainrings in roughly the right location, it'll be fine.

Yes, that's one of the most beautiful cranks ever made. I've got the same model-year XTR crank on my road bike (built back before road triples were common), and it's quite pretty too. It was designed for a 107mm bb, but since it's on a road bike with narrower rear spacing I'm using it with a 103mm Dura-Ace 7410 BB that I found on eBay.

So: you can buy the Sugino or FSA new, or look for a used Dura-Ace 7410 bb on eBay (I paid $30 for mine, and it wasn't much used and is very smooth).

As Danno said, if you use the same length spindle, your chainline and front derailler won't know the difference.

I still run the Dura Ace 8 STI Gruppo on 3 of my bikes of which that crankset is a part. Make sure you get the BB Ti bolt/covers that come with them.
Check e-bay for the matching 103mm Dura Ace Shimano BB. They pop up NOS or used. I use the Park BBT-1 tool.

The Phill Wood BB should work fine just make sure you get the rings and the required tool and be prepared to do some BB centering as the RHS ring does not have a flange but no biggie.
