The CCP-44 is specifically designed to remove cranks using an Octalink or ISIS Drive bottom bracket interface. Key Features: It uses a long, comfortable handle and a fine thread for the leverage needed to remove tight crank arms. Unique rotating tip design has been updated over the CCP-4 and ensures even smoother operation and longer life. The CCP-44 will not work on crank arms that fit standard square, tapered bottom bracket spindles. Weight: 1lbs (Manufacturer claimed).
