Spindle length for Sugino VP triple?
Who knows the proper spindle length for a Sugino VP triple? It's not listed on Velobase. A Google search turns up a 13-year-old thread on the Bicycle Mechanics forum (https://www.bikeforums.net/bicycle-m...ple-crank.html) in which a bunch of people float a bunch of wild-ass guesses ranging from 107mm to 127mm. No doubt it's somewhere between those extremes, but I'd like to narrow it down a bit more than that....

there are a bunch of variables in play here but I'd suggest a spindle in the 120-122 mm range.
you will have to try it and see.
alternatively a Phil BB gives you 3-5 mm of lateral adjustment to get the perfect chainline.

Yes 121mm, with a bit of offset to it.
I tend to set up triples with the minimum of clearance between the chainstay and small/middle chainrings and bolt heads, to better preserve chainline while passing the riding miles in the big ring.
I'm never sure though what I will come up with in a pinch from my existing bottom bracket and spindle assortment, so things can get creative. Possibly even a 118mm cartridge bottom bracket with a fixed-cup spacer, whatever the chainstay clearance situation dictates. On lesser frames, I might even take a hammer to any location along the right chainstay where the small chainring bolts perhaps collide (might have done this on my Six-Ten as I seem to recall).
There can also be the consideration of how far that the front derailer cage can retract when shooting for the shortest bb spindle option, which can add time to the parts-selection, installation and sorting. I tend to find such efforts worthwhile as I really loath excessive chainline.
