11 speed chain, 9 speed cassette

[mtechnica]

Will it work? I’m guessing it will but I was wondering if anyone here has tried.

INDEED...will work just fine

9 thru 11 speed cogs are the same thickness. The difference is the spacing between them.

Thanks for confirming

Depends. Modern shifting systems that don’t ‘overshift’, then center(like shimano) depend on a certain chain width so it’ll be ‘grabbed’ by the next cog ‘up’, when shifting to a lower gear. If the chain is too narrow, on a system that may be worn some, the cog may not ‘grab’ the chain.

Besides, 9s chains generally cheaper than 11s…

So while on the subject…….I have a few spare brand new Shimano 10 speed chains, are they ok to use with an 11 speed groupset…….

Probably not. They ‘May’ shift but they will be noisy.

10s Dura-Ace chains go for almost $100 each on Ebay these days.

Both of the comments from oldpotato, regarding narrower and wider chains, reflect my experiences exactly.

I was asking because I impulse bought a 9 speed bike and all I had was an 11 speed chain. For now I’m using the 9 speed chain because it passed the wear gauge but at the time I assumed it wouldn’t have lol.
