many thanks everyone - will take a look at the options mentioned. As I am heading to Sardinia to race may well go full compact!
The Praxis ones match the curves of your Dura Ace rings, so that's nice.
You can get FSA chain rings in 52 & 36 (110BCD) that are Shimano compatible.
ChainReactionCycles, UKBikeStore & Wiggle all do them (alphabetical order
... as do others I'm sure, but those are the ones I can remember off hand).
Praxis do a Pro Compact 110BCD - 52/36 chainring set, available from Upgrade Bikes
there's certainly a 52/36 in ultegra 6800, but that's an 11spd groupset
That's odd, I could have sworn I saw an Ultegra 6800 52-36 crank option somewhere. Must be imagining it!
Shimano doesn't do 52/36 chainrings for any of the 10 speed systems. You can get 34, 39, 50, 52, 53 tooth chainrings from Shimano.
SRAM does 52 and 36 for 110 BCD, if your crankset is also 110 BCD it will work. Shifting and crankset stiffness will suffer though.
I'm 99.9% sure that Shimano 11 is the same as 10, unlike Campag, where 11 is designed for a narrower chain.
Had a quick look, you would need to swap the whole chainset as they changed the BCD, so that's an expensive route!
