..What is this 'special tool' needed to install a 'new link pin' on the 9 speed shimano chain? Is it just a regular old chain breaker???? .
The installation-specific link pin is longer than an usual pin. Not all chain breakers can have their plunger backed out long enough to accommodate this. If yours can gape wide enough, you're OK.
