Can a 10spd chain be used with a 9speed cassette and rear derailer?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Yes, The distance between the plates on each link is the same distance. The plate itself is thinner on the 10 speed chain to allow for the closer cassette spacing.

What everybody else has said, with the additional warning that you shouldn't try the reverse -- a 9 speed chain shouldn't be tried on a 10 speed cassette.

but why would you want to use a 10 speed chain with a 9 speed setup? Lots of anecdotal reports that 10 speed chains are a little more prone to seperate because of how thin they are where the link engages the pin. Obviously you need a 10 speed chain with a 10 speed setup, but if your running 9 speed, why not use a cheaper, stronger 9 speed chain?

Not to hijack the thread, but what is a good replacement 9 speed chain for a Shimano 105 setup? Are there any that dont rust?

None of them will rust if you properly clean and lubricate them regularly.

But to answer you question more directly I would use either an HG-73 Shimano chain (or higher) with a SRAM powerlink or a SRAM PC-951 or higher. More money gets you coatings that resist rust (but again if the chain is lubed it wont rust) and they get lighter...they all shift about the same.

The kind that don't rust are the kind that are looked after by the rider. Anyhow, I favor SRAM 9-speed chains. I just put on a fresh PC-971. The "gold link" is very handy for tool-free removal (for cleaning, for example).

A friend of mine went to the LBS and got a compact crank (R700) installed a few months ago on his Madone.
Shifting seemed good afterward. Then last week he got Nokon cables installed (with too much housing length I might add) but they didn't shift properly. The front shifter would need 3 clicks to get up to the big ring and even then the chain still rubbed on the outer plate. He tried messing with it last night and got the inner wire messed up so he came over for me look at it.

I fixed the inner wire issue and the housing length issue but for the life of me I could get the front shifting proper. I decided to take a closer look. Upon inspection I noticed the FD was a 1/2" from the chainring, way too high. I found when I tried adjusting it that the braze-on mount on the Madone doesn't have a long enough slot to get it low enough to the big chainring. (Design flaw of the Madone.)

Then I noticed that the FD is an Ultegra 6600 (another LBS mistake). The 10-speed FD has too narrow a cage to effectively accommodate a 9-speed chain and have the shifter work the way it should. That's why I was thinking a 10-speed chain might work with the 10-speed FD better.

Not true.....when your bike is on the car rack and riding in the pouring rain for 10 hrs 2 days straight they will tend to rust despite regular cleaning and lubing....
