So if you have a BB30 frame, you'll need this specific adapter to install your Campagnolo Ultra-Torque crankset. The adapter consists of two black anodized aluminum cups that press into the PF30 shell. Once installed, the Campy Ultra-Torque crankarms with integral bearings may be slid into place and bolted together. Note: We strongly recommend a shop quality headset press and properly sized mandrels be used to install the adapter cups. Be sure to install the adapter with the groove on the drive side, and don't forget to install the wire clip.
