I've been thinking about this recently as I'm doing some basic mods to my old Voyageur. I don't see many 6 speed chains out there, and I've been buying only KMC chains so far, so happened to notice that the description on many chains have a wide range of speeds. Like the

so are 6-8 generally all compatible, or do you really need to stick to "1 speed off". I mention specifically, because I have 6 speed freewheel, and looking at this chain (on KMC's site it is just listed as 8 speed but is very common for sellers to label it as 6, 7, 8 speed compatible).
