I got the RK Chain Breaker/Riveter. I ordered it online from the Sprocket Specialist or Sprocket Center, I don’t remember which one but it was the tool that they used and recommended.The D.I.D tool looked pretty nice and solid but it was a lot more money.Anyway, the RK tool works flawlessly.Heard some not so good things about the Motion Pro tool .The RK tool pressed the pin out to break the chain effortlessly without grinding the head off.Too bad I live in Brooklin.
