Is 10spd chorus compact crank compatible with 11spd?

[Hilltopperny]

I have a 10spd chorus compact crank on my Mxxxxxo and a bunch of 11spd chorus parts hanging around. I know 11spd cranks work fine with 10spd drivetrains, but can I run 11spd with the 10spd compact?

The pros were doing it when 11spd came out.

[AngryScientist]

yup, no problem.

10-sp crank, 11-sp other stuff. works perfectly.

With UltraShift front der, no problem. Use an 11s chain(match cogset, not chainrings).

Agreed. I have been seeing a lot of stuff labeled as NOS, but clearly it has been used.

[R3awak3n]

those are way overpriced too, you should be able to pick some of those for $100-$120 in great shape

That crank is 9 speed. Anyone tried 9 speed rings with 11?
