Master Chain Tool with Peening Anvil

Designed to work with the tight tolerances and narrow profiles of 10 to 12-speed chains, but also works on most other 5 to 9-speed derailleur chains. The CT-4.3 is a powerful, precise tool designed to quickly and accurately remove and install chain rivets. Without a doubt the most accurate chain tool we’ve ever built.
