The Universal Chain Breaker Tool from Sunlite belongs in every cyclist's toolbox. You can use the Universal Chair Breaker to shorten a length of open loop chain, or to repair and replace a damaged link.

Note: The commonly used term "chain breaker" is something of a misnomer. Perhaps a better phrase would be "chain pin pusher" as it describes the process more accurately. To use one of these handy chain tools, the link is placed in the slot, the lever is rotated, the screw is turned, and the chain's pin is pushed from the linkage. You can completely remove the pin, or leave it partially in place. Then you can use the tool to push the pin back into place completing the adjustment or repair.
