9 speed chain on 10 speed crank

Has anybody run a 9 speed chain on a Shimano 10 speed Dura Ace or
Ultegra crankset?
I think Shimano says not to do this, but wondering if it is possible
upgrade crankset and not everything else. What is the difference in
chaingring spacing between a 9 and 10 speed?

Thanks - Joel

If you're not running a 10s cassette, there is zero need for a 10s
chain. The spacing of the front sprockets is the same for 7/8/9/10.

Hi Joel, I just recently upgraded to an Ultegra 6600 (53-39) double, and
did run into some chain compatibility issues, so here is what I learned:
First off, my bike has a full Ultegra group, with a 9-sp cassette, and
these new cranks replaced my Truvativ Rolleur compact (50-36) that had
come stock on the bike. The short answer to your question is yes, you do
need to run a 10-sp chain with a 10-sp crankset. While I can't comment
on comparative chainring spacing between 9 and 10 sp cranks, I can tell
you that after installing the Ultegra cranks and throwing on a new SRAM
pc-59 chain (a 9 sp model), I immediately noticed that the chain would
rub quite severely when I had the bike cross geared in the front 39T
ring, up through the 12, 13, 14, 15T rings on the cassette. This rub was
not from the chain hitting the derailer, but instead from the chain
rubbing on the inside wall of the front 53T chainring. This issue was
remedied simply by taking off the 9-sp chain and replacing it with a
10-sp (a KMC x10). The chain rub went away instantly (although it still
does rub slightly when it's completely cross geared out in the 39-12,
which is understandable). So, while a 10-sp chain is a bit more
expensive than a 9-sp, it is a necessary part of the upgrade it you want
to retain the full range of gearing on your bike. Well, good luck! I
hope my experience helps make your crank conversion a happy one.

David,

So you are using a 10s chain with a 9s cassette. I thought that was a
problem, is it working ok for you?
Yes it makes sense that the 9s chain would rub on the big ring assuming
the 10s chainrings are closer together.
Thanks for sharing your experience.

Yes, using a 10-sp chain will work just fine on a 9-sp cassette,
however, the 10-sp's narrowness (as compared to a 9-sp) may require you
to adjust your rear deralier tension to get things shifting properly.

yes...Sram and shimano 9s chains.

Not significant...no need to do anything, just put crank on, adjust
front der, go ride.

This is common with 9s systems as well....a 10s chain and a 9s cogset
is a poor idea and not necessary.

10-sp (a KMC x10). The chain rub went away instantly (although it still

I guess the idea of chain to big ring rubbing in gearing that is
duplicated by shifting to the big ring and bigger cog deosn't inspire
me to use a more expensive, thinner by 1mm, 10s chain on a 9s cogset.
I haven';t tried this, 10s chain on a 9s shift system since there is
not reason to do so...but I may try it if two bikes are both needing
chains at the same time, 9 and 10s...but again, Sram 9s chains work so
well on so called '10s' cranks, shimano, Campag, FSA, Truvativ, I see
no need.

You'll notice more remarkable difference between the front shifting
than the rear cassette by using different chains. Different design of
chain will upshift faster and release to lower rings cleaner for less
chain drop. It's most noticed when setting up compact, road cranks.
I still haven't figured out all the voodoo of getting it perfect and
just use Jump Stops.
