Re: removing and adding chain links on motorized bicycle chain
the park chain breaker you were looking at is a good one and i believe park has a lifetime warranty like craftsman. for the top use the one you took off use the 2 pieces. on the bottom of this picture and use your tool to press the pin. nothing needs to be rounded off. they fit tight. alot better then a master link and stronger. to me the master link is the weakest link so i do away with them. i can acutually do it this way faster then with a master link also. the cheap kmart schwinn breakers etc are the ones that bend and break.
