I think those are what I have on my Tarmac. The ultra bike usually has the cheaper alu version but they're basically the same thing. FSA Omega or something similar.
Maybe it is alu as well, just a more expensive version of the Omega? I'll go and scratch it to see what colour it is underneath the white paint :)
It's on my normal road bike so I never clip anything on to it save for Garmins and Exposure lights.
