Park Tool Campagnolo 11 Speed Rivet Peening Bicycle Chain Tool CT 11

After pressing the special connecting rivet into a Campagnolo 11 Speed Chain and breaking off the pilot, Campagnolo requires the end of the connecting rivet to be peened or deformed to prevent chain failure. The precision machined CT 11 is used to accurately perform this critical process. Note: The CT 11 will not install or remove chain rivets. Its sole function is to peen and secure the end of the Campagnolo 11 speed connecting rivet. The Park Tool CT 4.2 Master Chain Tool or previous model CT 4 is used for rivet installation and removal.
