Pulling off crank arms is the only way to thoroughly service bottom bracket bearings. The unique universal design of the CCP-2, originated by Park Tool Co., eliminates the need to have a different puller for each different brand of crank set. The double-end puller nut fits all cranks with 22mm x 1 and 23mm x 1 threads. A special "floating", hardened tip provides long life and smooth operation. The thread lengths of the CCP-2 have been increased to accommodate new, deeper crank arms and the long handle provides plenty of leverage.
