My only other comment is that although Shimano cartridge bb's are inexpensive, don't take that to mean they are not extremely durable, no-maintenance, and for some, preferable to even high end cup and cone bb's.
Thank you for a very thoughtful and helpful response
from one ProTour owner to another. I really appreciate it !
Yes, as you say and from what I gather a 127.5mm catridge BB with spacers should do the trick. Everything you said is true- the Shimano style cartridge BBs would make a very good solution. I'm not opposed to them in any way, but my bike is 100% early/mid 80s in terms of components so a part of me is really hoping to maintain that. But in lieu of a vintage- Sugino wizard I think you have offered a very practical and functional solution.
Its rolling on some lovely Sansin sealed bearing hubs so add a sealed cartridge BB and what will be left to maintain
?
