I currently have 2011 Super Record CT (110BCD) cranks and I wonder if I can upgrade it with new Evo 36/52 chain rings. Does anyone know are they compatible?

You would have to make sure you got record chainrings, P/N FC SR252 and FC SR 036. Lower level chainrings use conventional nut and bolt system and the Record spider holes would not accommodate them.

See the drawings here http://www.campagnolo.com/repository/documenti/en/SPARES2013-PART_A-27-11-12.pdf

Thanks for your reply. Based on spare part document you linked and other info I found. It seems that holes in new evo chain rings are smaler. Therefore new screw set is also needed. However new screw set should make them fit to also SR 2011 CT spider. Correct?

Actually I wonder if there is any difference between SR 2011 and 2013 cranks?

I'm not aware of any change to the cranks over the past few years, but the way to check is to compare from the spares catalogs of the relevant years. They are all under the Campy "tech docs" section.
