Park Tool CCP-44 Cotterless Crank Puller
The CCP-44 Crank Puller is specifically designed to remove crank arms from splined Shimano Octalink and ISIS Drive® bottom bracket spindles that do not use a "One Key Release" system. It uses a long, comfortable handle and a fine thread for the leverage needed to remove tight crank arms. Now with a stronger rotating tip system to ensure smooth operation and long life.
Note: The CCP-4 will not work on crank arms that fit standard square, tapered bottom bracket spindles.
