I know this is going to be easy but a search did not find the result I was looking for. I broke a chain on the way to work this morning and stopped and got a dura-ace chain at my lbs. I asked the guy at the shop and he said it should not be difficult to install and that it should work right out of the box. So I got it on my bike the correct way but it seems the connecting pin sticks out some. Do I bust this off or what? I have never worked on a chain before and I am learning bike maintenance as I go. Any help would be appreciated. Also, how do I know if the size is correct? Everything seems pretty tight without being too tight so it seems right but not sure.
