I'm wondering if all 10-speed chains fit to 3x10. A lot of webshops say that the chain is "for road bikes 2x10" or something like that. Or nothing at all. The chain I have right now (Shinano CN HG-54) is "ultra narrow", but I'm not sure if that's because it's a 10-speed, or if there are sizing issues between 1x10, 2x10, and 3x10.
I appreciate any input!
