I recently had a KMC Missing Link blow up on me and it almost left me stranded but I happened to have the old SM-CN79 that came with my bike originally (two chains ago) in my seat pack. That at least got me home.
On the way home from work today, I stopped and picked up a new Missing Link and also a new Dura Ace Chain. I noticed the Shimano quick link isn't really available anymore but anybody else experienced total failure of the Missing Link?
I'm considering putting my chain back together with the normal Shimano connecting pins.
