Anyone know if there's a Shimano square taper CARTRIDGE bottom bracket that I can put a square taper Shimano Adamax AX crankset on? My buddy wants one. I have a Shimano Cartridge BB-UN51 but is seems as if the taper is different on it than on the crankset and thus the crankarms slide all the way to the shoulder of the spindle and the crankarms can be wiggled.
So, 1, are the tapers different and 2, is there a Shimano cartridge bottom bracket that'll work with the Adamas AX crankset?

Thanks and cheers

That's a great source but unfortunately the PDF documents I have show a splined bottom bracket not a square taper one. Thus I don't know if it's ISO or JIS but I think it must be an ISO one.

See
http://velobase.com/ViewComponent.as...8-9de236236248

which seems to list a Shimano BB-SL31 bottom bracket as usable with
the Adamas AX group. But noted as "Specialized BB specifically for the
ADAMAS AX series cranks: FC-AD11 / 21 /22." and " Base level of the
'AX' groupsets produced by Shimano, the Adamas group was supposed to
be a touring minded group. It ended up being only produced for a few
years."

The date seems to be "1983"
