I get lots and lots of tech questions (obviously these people have never read my confessions of mechanical stupidity). I was sent this link to an article on Velonews regarding narrow 10 speed chains. I found it to be very informative and thought I would share it with you all. I myself have had some issues with 10 speed chains... but admittedly, that is mostly an issue of wear and improper installation.
Anyway, I found the information to be worth sharing. It's a good read (compliments to Lennard Zinn- who happens to be a really cool guy).
