HG chain or KMC

Help please. Can I run a 9 speed KMC chain on my STX RC 7 speed chainset? A sticker on the 1995 chainring says "Shimano HG chain only" - but I guess things have moved on a bit over the last 20 years.
 
Re:

7 and 8 spd chains are the same and brand inter-changable, but a 9 spd chain is of a different guage (than 7/:cool:, so will not work properly.

I believe. :idea:
 
9 spd chains work wonderfully with 6/7/8spd systems oh and dont forget 9spd too!

The inside is the same width with the outer skinnier for 9spd systems.

Well I was going to advise against because I didn't know that either! Had I known, I probably wouldn't have this stockpile of Sram PG870s for running on anything 6/7/8speed... :facepalm: :LOL:
 
This is interesting: well to me it is. So if I'm struggling to find NOS rings for my 7 speed STX RC chainset I could swap to a 9 speed chainset with a 9 speed chain and keep the 7 speed screw-on freewheel at the back. Am I right or am I right????

Yes. Sometimes there can be a bit of extra chain rub but if you have a good chainline it wont show itself
