Hello Scrod. Today I was putting on my KMC Z710 chain, but on my initial measurement I was 1 link short. I attempted to add a link on, but it was quite difficult to push the pin in with my crappy chaintool. At this point is was quite late so I went to a large sports store that deals with highend roadbikes to have it checked out. They proceeded to tell me I was sh*t out of luck and that it isn't recommended to add a link back to my chain. Is this correct with the KMC Z710 chain?
