chainset compatibility

[barney rice]

I'm looking at replacing my chainset and have a few queries about compatibility with remainder of groupset;

Will 10 speed chainset/chainwheels work ok with 9 speed (Campag Chorus) not for racing general riding, sportives etc:

Will TA/Campag chainwheels fit SRAM spiders?

 

[Hairy Wheels]

9 speed works fine on 10 speed cranksets (I recall seeing Horner at some races with this setup maybe 5 or 6 years ago).

No, Campy or TA rings with the same bolt circle will not fit SRAM spiders.

Just to add, a Campy Centaur Ultra-Torque (2009/2010...not the 2011) is a great crankset for the price.
