Once you use a Split Sprocket, you may never want to use a setscrew mount style again. Removal or installation is a breeze. Can be used in virtually all applications. An additional benefit to Black Ace’s split sprockets is that the shaft/keyway security is much tighter than a typical setscrew mount.
