That is, the ends are pressed to expand to lock them into the plates. Technically speaking, they are rivets, not pins. When one is pressed out, it removes a small ring of metal from the plate as it pushes through. Replacement pins are a slightly larger diameter than the original rivet, to account for the metal removed. It's been years since chains started using rivets, but replacement pins have only recently become available. Not all new things are scams or bad ideas. | |

For a given chain and chain tool you need to practice on an old chain and count the number of turns to push the pin so that the one end is just flush with the plate. Then write that down somewhere where you can find it when you need it. | |
