So for a single speed setup any of them will work, but the higher the speed, the lighter the chain will be (I assume.)
I am wondering why the surly cog only said 6-9 sp. Is a 10 speed chain too thin? AND.. Would you get less (or slower) chain stretch on a 6 sp chain because there is more metal to wear through?
Actually, it's got more to do with the way the pins are riveted and the design of the side plates. I'd avoid 9 and 10 speed chains unless you have an application that specifically requires one. They require special pins to re-join the chain (or masterlinks) and are a lot more demanding about how they are assembled. They are also more money.
