Searched a lot on the net for a BSA 122.5 ISO square taper bottom bracket 68mm but having no luck. This is for a 1980s Campy triple chainset, currently has a 120 ISO spindle but actually measures 117 with quality calipers, also is an asymmetric spindle if that matters. I want a 122.5 to improve the chainline. I know you can use a JIS spindle and the ISO chainset will be 4mm+- farther out (Sheldon Brown and other sources) but I don't want to go that route. I tried using a JIS but the Campy didn't begin to seat properly on it and I don't want to screw up the chainset. Any information on where I can find one or other relevant info will be greatly appreciated! thanks

Phil Wood is your friend. Andy (who recently had a very old Phil BB have new bearings installed and decided to have them shift the axle 1.5mm)

Phil Wood is awesome. Sadly though none of the older PW employees are still around and knowledgable about my bike. I really am curious about their frames they made for the Apple VeloXS race team. They were nice enough to reach out to a former engineer but he couldn't remember much. They make excellent stuff and I highly recommend it especially in the odd square taper department as they probably make it or have made it and could make it again. Plus that red Phil script logo is just so sexy for some reason I see it and I swoon.

Brian- I have a few older Campy spindles on my shelves. Can you provide a few dimensions beyond the overall length so I can see if I have one that might work? I ran home drilled (unfortunately for 86mm bolt patterns and not 74...) Campy NR triple cranks for a long time before the 41T middle limit became intolerable. Width between bearing shoulders, bearing shoulder to end on both sides/ends.

Back in the day we would just reach into one drawer and or another and test fit TA, Stronglight, Campy, Nervar, Sugino and that new kid Shimano (or Takagi). Andy

Brian- I have two axles that might work for you.

Sugino MT-68 silver. 38.1 x 52 x 29.3 (aprox to a tenth of MM or so). Used but look good. Three tiny pin prick sized marks on ball tracks (I'd use it again w/o hesitation). Overall length about 118.8.

Sugino MT-68 black 37.3 x 50.6 x 28.7 (aprox). Used and looks more worn but has slightly cleaner ball tracks. Overall about 116.8

Both being Sugino Mighty are Campy tapers and fit into a NT crank arm as one would think is correct depth of overlap. Not sure if this matches later Campy taper fits as I never ran any Campy cranks of the 1980s vintages.

If you think either might work for you let me know and we'll talk turkey. Andy
