I have an older XT Crankset which uses the ES70 BB. My question is whether the ES71 BB can be used with this crankset or is there a capatibility issue? I haven't tried it yet, just wondering before ordering a new BB.

I believe they are interchangeable. The only difference between the two that I am aware of is the ES71 has a special rust proof coating inside the pipe spindle so that when used with the XT M752 cranks, which has hollow crank mounting bolts, won’t rust.

Thanks, I appreciate the info. I wasn't sure what the difference was, just wanted to make sure it wasn't a compatability issue.
