Master Chain Tool

The CT-4 was discontinued in 2010. Our current Master Chain Tool is the CT-4.3.

Specially designed to work with the tight tolerances and narrow profile of 10-speed chains and most high quality derailleur chains. The CT-4 is a powerful, precise tool designed to quickly and accurately remove and install chain pins. Without a doubt the most accurate chain tool we’ve ever built.
