Bought the M.P. chain tool kit. On higher end chains, this pin can be a real pain when it snaps. I buy a couple at a time, it works easy enough, but there is fine line between a pin coming all of the way out to almost coming out.
I bought the tusk riveting tool and the press pins broke after one use. However these motion pro pins work with the tusk tool. so if you have the tusk riveting chain tool and broke the pins these motion pro pins with fit the tusk tool. and around 6 dollars a pin the price is just fine.
Don't let the weekend go down over not having a couple extra. When you do need these, there is nothing that will help you but these. They are the final in a quick chain fix and without them you are pushing/towing it. They are cheap enough to keep extras too.
