Full Speed Ahead 110BCD 10 Speed Chainring replacement options

My 2012 Synapse 105 needs new front chainrings, currently they are FSA 10 Speed, 110BCD 5 hole rings with 50 and 34 teeth with the following part numbers:
Large (50T) 2511K WA291-50T
Small (34T) WB204-34T 1GZY2

I have searched the FSA site but I can't find these parts at all. I know that soon after my bike was made Cannondale moved to 11 Speed and I am wondering if the 11 Speed versions of these are the correct ones to use? I am struggling to work out the correct part numbers.

Are there any non FSA rings that would work with my FSA crankset?

    Any other 110bcd 5-bolt chainring will fit. 10 or 11 speed..

    It will probably cost you £40-50 to change both rings. Stronglight make aftermarket rings that are probably the cheapest / best value out there. But personally I'd pick up any cheap BB30 chainset you can find on eBay as it's something lots of people sell nearly new to fit a PM/ change ratios / make a groupset match. Doubt it will end up any more expensive.
