Bottom Bracket **********
Another question on BB's.........
My current BB is a Shimano BB-UN26 with a Shimano XCT crank, and my question is how do I know if it's ISO or JIS, or are these new BB's all ISO?

Shimano is all JIS. As a general rule most bottom brackets won't say on their packaging what taper they are so you have to know what cranks they are for. Shimano, SR, Sun Tour and most Suguino are JIS. All Campy and some other European makes are ISO.

Yes, I was refering to square taper only. Thanks, that is something I did not know. I was under the impression Shimano made both JIS and ISO and that was confusing the heck out of me. Thanks so much for you help.
