Howdy all,

Probably should have asked the question here first, but I've just ordered a Shimano R700 compact crank ro replace the DA 7400 52/39 on my Specialized Epic Pro road bike. I'm under the assumption that I will need to change the bottom bracket to one of these:

I've already replaced the rest of the drivetrain with 7800.

Besides tools, anything else I will need to perform this switch? Are there any other concerns that any of you might have with this?
