I was assembling my new road bike and on the first ride I discovered the the link that I put the new chain together with is now stiff and I can't get it free with oil. It is a Shimano Ultegra chain and I had to take out a couple of links and connect it together. It is now stiff, I did use the break away chain pin that came with the new chain.
What to do now? I thought that once you put one of these connecting pins in you were not supposed to remove.
