Is your BB 24 or 30mm? Shimano is 24mm, so if your bike uses BB30, you will need not only the Shimano BB, but also an adapter. Both are inexpensive.

OK, so that means he can use the old BB. However, a Shimano BB is cheap enough. I would replace it, rather than have to go in there later when the cheap FSA one goes south.
