raced a great cross race today, but my derailleur kept on clunking around.
came home, and discovered that the problem was a stiff link. My regular tricks didn't work. Any ideas?
It's a shimano ultegra 10-speed chain, so I'd prefer to rescue it rather than scrap it--it's pretty new and has seen fair upkeep. There's what looks like a bit of scoring on the top of the stiff link which I'm guessing may have been caused by shifting under load.
