Anybody know if Shimano Ultegra FC-6650S 50 Tooth 10-Speed Compact Chainring will be compatible with my ultegra 9 speed chain?

It won't fit a 6500 Ultegra crank, in case that is what you have...

Different BCD.

I answered about a chainring, not a crank. Sorry if my answer was misleading.

Ok yeah I have a 6500 crank, I thought it was 110mm

Yup. The chainrings didn't get thinner, just a little closer together. 110mm bolt diameter tho, no fit onto a 130mm bolt diameter crank.

Thanks I'm going to get a 50 tooth with the 130 bcd then...
...now we just need a bit of spring to show up.
