As my brother John knows too well, I'm not much into the bike maintenance thing but I'm working on it. Today I put new chains on my cross and road bikes. (I now have a tool that checks chain wear.) I did the cross bike first and it went well. I counted the links and laid them out so they matched.
New chain on the left needs shortening.
I made a slight mistake with the new chain for the road bike. While placing the chain in the tool to remove the excess links, I moved the chain one link off and pushed the pin out of the wrong link. Since the Powerchain pieces won't connect to the outer plates I removed that link, which I believe makes me two links short. I rode the bike and went through all the gears. If I'm on middle chain ring and the smallest cog in the rear, I can't shift onto the big chain ring. But if I'm on any of the larger rear cogs, I can shift onto the big chain ring and then down to the smallest rear cog. There's still an "S" and the rear derailleur is not pulled too far forward. So it doesn't seem too bad and I'm guessing I'm okay until I get another chain in a couple of days.
