I just went back to a Shimano chain. For emergencies, rather than using a missing link, I considered just bringing a couple of unused links and a replacement pin. However, I don't want to carry a pair of pliers.
I have a Crankbrothers M19 tool set. I think I might be able to use the #3 spoke wrench on the chain breaker to add a little bit of leverage but not much. I might also be able to just use the end of the chain breaker but the opening is fairly large. Anybody have any thoughts of how to snap the pin without pliers?
