Which modern Bottom Bracket for a Shimano Arabesque Crankset?
Can anyone tell me which modern (sealed cartridge bearing) BB would work with a 600 Arabesque crankset? I am thinking maybe a Shimano UN55 in 68x115. Anyone know for sure?
Thanks

116 JIS taper, I think. The 115 will probably be fine.

Adding my "+1" here.
For most of the square-taper equipped bikes that I own, I end up preferring a shorter spindle myself for the better chainline, allowing me to stay in the big ring more of the time with nary a concern about "cross-chaining" effects.
I also always use modern chain as well, for the smoother transmission across a wider range of gearing combinations (thinner being better in terms of shifting performance in back and for front derailer cage clearance).
Usually the only problems with a much too short spindle will be chainstay clearance or a lack of downshifting power from the front derailer, but a thin fixed-cup spacer fixes that.
