10 spd and 9 spd chain

10 spd chain would be thinner, i wouldn't know really, anybody else ?

Will a 10-speed chain work? I don't know. But 10-sp chains are more expensive and apparently don't last as long, either. If it were me, I'd tell them "thanks, but if you don't want to carry 9-sp chains, I'll just mail-order them."

Believe the interior width of both 9- and 10-spd chains is the same, so it should be possible. Indexing will probably be a bit more finicky. Please let us know how it works out.

FYI - 9-speed chains available on ebay right now for $14+free shipping (buy-it-now) or less at auction prices.

And if you don't feel good about using ebay both Jensonusa and Nashbar have 9 speed chains starting around the same price. I hope you mean that your bike shop is just out at the moment and not that they don't carry 9 speeds. Any decent bike shop would have chains on hand for any speed of drive train from single on up.

hi, i am using a 9 spd gear. i was told i could use a 10 spd chain. so is it ok if i use a 10 spd chain because the bike shop which is nearer to my house doesn't carry stock for 9 spd chain.

No, 10s chains are much thinner and your shifting will suffer, Find a new bike shop. Any shop that doesn't carry 9s (and 8s chains) are being lazy.

It's all about the rear sprocket. 10s = 5 rear and two front. If yours is 9 spd then let them see it because it's a rarity. Is yours a 9s hub gear with a single rear sprocket? If it is then a thicker heavier chain is best.

(I have a 9speed...Sturmey-Archer 3s rear and a 3s front, and it's a rarity).

To my understanding it will work but I would go with the wider more durable 9 speed chain if at all possible.

Ummm...not quite. A 10-sp chain means it can be used on a 10-cog rear cassette. A 9-sp chain can be used on a 9-cog rear. 8-speed chain is for pretty much everything else. For example, I just put a new 8-sp chain on my 12-speed bike (2 front, 6 rear). It's poor nomenclature since it would be intuitive for a 10-speed BIKE to get a 10-speed CHAIN, but such is not the case.
