BB30 was the first new bottom bracket standard to appear in the aughts. Cannondale devised it and made the standard available to everybody. Today, the BB30 ranks are swelling. It makes sense that Campagnolo would offer a cupset to adapt their Power Torque cranks to the BB30 standard and thus we sell this Campagnolo Power Torque BB30 Integrated Bottom Bracket Adapter. Once installed in your frame, your Power Torque crankset will slide right in. Bolt the two halves together and you'll be ready to ride. The BB30 standard refers to a 68mm wide shell with a 42mm inner diameter. Note: Be sure to install the adapter with the groove on the drive side and install the wire clip after you insert the drive side crank assembly.
