Rivet Peening Tool for Campagnolo® 11-Speed Chain

The CT-11 has been discontinued and replaced by the CT-4.3.

After pressing the special connecting rivet into a Campagnolo® 11 or 12 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.

CT-11 Features

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 or 12 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 eliminating the need for the CT-11.
