1.0 out of 5 stars What sort of vendor would omit the chainring sizes?
These chainrings could be any size ranging from 50/34 to 52/38. Unless the vendor says what size the chainrings are, don't buy it.

I hope this can solve your doubt if you have Ultegra Chainring Set. I read about its review and decide to purchase it. I have not test the product as I just install on Colnago CLX with Ultegra Set. I think the review you search on the internet can speak for itself ( [...] ). The chainring I bought was the BCD 130 53/39 Chainring sets (The 53/39 is not specific in the product description which I find it is important). You need to also purchase a chainring bolt set (5 pairs) of size M8X0.75mmX8.5mm ( tested it can be used) or you can try Shimano Ultegra FC-6601G Double Chain Ring Bolt set/10 or Shimano DuraAce-7800 5-arm CR-bolt set, M8x9.1-sil which I think can be suitable as it is only 1.1 mm longer. The chainrings set was suitable for the Ultegra crank arm. After I installed, the gear shift was as good. Hope this clear your doubt if you have Ultegra chainring set.
