Chainring for Athena Ultra Torque

[Crossdrop]

Hey there,

I have worn out chainrings on a Campa Athena Ultra Torque Compact Crank Set. Unfortunately, OEM chainrings are not available. As I'd like to replace with silver chainrings for design reasons, I already found out I have to go to 10 speed chain rings, which however will work fine, as the inner diameter of the chain didn't change from 10 to 11 speed and people are doing fine. However, there are two different chainrings, called Type B and Type C. Type B is suitable for Ultra Torque Veloce, Mirage, Centaur Carbon & Fulcrum R, Type C would fit for Ultra Torque Record, Chorus, Centaur Alu, Fulcrum RS or RRS.

From all I know, the way they connect the chainrings with the bolts has changed in between around 2010 or 2011. Al I understand is that Athena Ultra Torque must be older than 2011. I hope there is any way to fit one of those rings onto my bike. Thanks for helping me out!
