Certain track-specific cranks still use an ISO-taper bottom bracket. it'll appear to work on the predominantly JIS-taper bottom brackets out there but isn't an exact mate and will likely cause problems. Specifically, the Sugino 75s and old Suntour Superbe cranks use the old ISO standard. Anything Shimano should be JIS. | |
