And if you are able to do your own wrenching, there are different sets of tools needed for different types of bottom brackets. For BB30/PF30 in particular, you'll need specialty tools to remove and install press-fit bearings. The Park Tool versions of those tools will set you back a little over $100. The specialty tools for most English/ISO/BSA bottom brackets and cranksets are generally less expensive. Figure $10-40, depending on your particular crankset and bottom bracket type. (You'll need some standard tools for any bottom bracket & crankset. Common ones would be hex (Allen) wrenches, socket set, & torque wrench.)
