Park Tool Rivet Peening Tool For Campagnolo® 11-Speed Chain


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 deformed or “peened” 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 or CT-4.2 Master Chain Tool is required for rivet installation and removal. The CT-4.3 Master Chain Tool has a built-in peening function and does not require the use of a CT-11.
