Park Tool CT 4.3 Master Chain Tool

All chains wear out and when they do, the replacement chain will often need to be "cut" to the proper length to fit your bike. To do this, you require a chain breaker, so why not pick the Park Tool CT 4.3 Master Chain Tool? Specially designed to work with the tight tolerances and narrow profiles of 10- and 11-speed chains, but also works on all other derailleur chains, including the Shimano® CN-9000. The CT-4.3 is a powerful, precise tool designed to quickly and accurately remove and install chain rivets. This is, without a doubt, the most accurate chain tool ever made by Park Tool.

• Integrated Link Pocket ensures precise alignment
• Replaceable rotating pin
• Includes removable anvil to peen Campagnolo 11-speed chains
• Note: The CT-4.3 is NOT compatible with Wipperman chains
