I've got a 6700 ultegra chain on my bike, along with a park tool combo that has a chain tool on it. Having never seen a broken chain, I'm not quite sure what to expect.
What does a typical chain repair involve, and what else do I need in my bag? 10speed KMC missing link to use for a repair? A spare shimano pin (I'm not even sure where to buy these)? Without either of these, I assume a repair is impossible. Is that correct?
