Sugino Mighty Competition Crankset- ISO or JIS, and what spindle length?
Just bought this crankset a few days ago, should arrive tomorrow. Looking now for a bottom bracket but don't know the correct taper or spindle length, and would appreciate any help anyone here can offer. Thanks so very much!
Stop reading my posts!
these were ISO (or more correctly: supposed to match the Campy Nuovo Record taper).
Spindle length is (according to Sutherland's) probably 114 for a 68mm shell and 115 for a 70.
Take this as a "guideline", measure twice and cut once.
Most of these cranks took an ISO 114mm spindle. As said above you may need to run a 115mm or 116mm if your BB width is 70mm.
The frame has a 68mm shell width, and I have a 115mm Campagnolo cassette-style bottom bracket that will fit it. I'll try that first and measure. Thanks again!
If you have nice BB with a 115mm that fits your frame you should be fine. Bolt everything together and I'm 95% sure everything should work good without problems.

+1, it almost HAS to work, given that the Campag bb is perhaps a bit more symmetrical than the Sugino MW68 spindle and thus the bb's drive-side cup flange can be shimmed out as needed.

Response quoting Sutherland's:
"As said above you may need to run a 115mm or 116mm if your BB width is 70mm"
How would the width of the bb shell affect the crankset's chainline offset at all though?
I never "got" why an Italian bb used a longer spindle than for the same crankset mounted on a bike with an English bb.
It's not like the rear frame spacing was wider or that the crankarm wouldn't clear the bb cups, so why the longer spindle?
