I would like to remove the bottom bracket to inspect the bearings. I've done what googling I can think of, and was overwhelmed with too much information. I don't know what type of bottom bracket I have, or whether I need a special tool to remove it. The specialized spec sheet says that the bottom bracket is "with crankset", whatever that means.

Do I need a special tool?

Specific instructions are most desirable, but a link to instructions for my particular setup would be appreciated as well.

Thanks for the help!
