Chainring compatibility


I have a FSA Omega 34/50 crankset on my 2012 Giant TCX 2 bike (9 speed) and would like to replace the worned chainrings. According to ChainReactionCycle, the FSA Pro Road Compact Chainring should fit (they say 9-10 speed) but on Amazon, they say 10-11 speed. Does it really matter if I use my original spacers? Will they fit? Any other chainring that you know of would fit?

BCD is 110.

I've found a lot of the online retailers cut and paste their descriptions and grab stock images for their pictures. It gets confusing because some will list 9-10 an others 10-11 like you said. So long as it's the same drivetrain (Shimano vs Campy) BCD (110 etc.), and number of bolts (4 or 5) it should work. I've mismatched a lot of cranksets, drivetrains, and speeds, and they all work about the same.

Try getting a whole crankset off eBay, it's usually way cheaper than buying the individual rings. For example:
