Okay - so I'll probably butcher this explanation for this call for help but here goes. I have a Litespeed Teramo and just installed a new FSA SLK Light crank with a new Dura Ace chain. However, I now have an issue where one of the rivets on the big ring is actually catching the chain. It occurs when the rear is on the smallest cog (12 tooth) and front is on the smallest ring (34 tooth). I clearly can't ride in this gear now, but what can I do to fix it? Can I shave the rivet down, remove the rivet (not sure what the purpose of it is), or is there another solution?

Thanks in advance for the help and please let me know if you have any questions. I tried taking a couple of pics of the rivet catching the chain.
