The Park CBP-3 is designed to remove and install the bearings from Campagnolo and Fulcrum Ultra Torque cranksets. The puller's arms grip under the bearing and pull up much like a fork crown removal tool. Bearing installation is straightforward and is done by simply tapping the bearing back onto the crank arm.
This tool is only compatible with Ultra-Torque cranksets. To remove and install bearings on a Power-Torque crankset, the
CBP-5 adapter set is needed.
