Instructions

    • 1

      Remove the rear wheel by loosening the skewer that runs through the rear hub.

    • 2

      Wipe down your chain with a rag to remove lubricant and dirt. This will make things less messy and will allow you to locate the master link.

    • 3

      Locate the master link. It can be differentiated from other links by its uniquely-shaped retaining clip.

    • 4

      Create a loop with the master link at the top. Use your pliers to apply force to the links on either side of the master link. This will cause the retaining clip to slide back. You can now remove the master link.

    • 5

      Now that your chain is broken, you can remove the unwanted length. Use your chain tool to remove the unwanted links by applying force to the rivet pin. Be sure to make note of your master link and remove the extra links in such a way as the master link will be able to snap back in place when you put your chain back together.

    • 6

      Now you can return your master link to the chain. Slide the retaining clip so that it snaps over both rivets. Now pull hard on the chain on either side of the master link to lock the retaining clip back in place.

      Be sure to lubricate your chain so that it will be protected from the elements and give you the best performance.
