Well, my local hardware store only had some spiral screw extractors that req'd me to drill in the head of the allen head. So I followed the instructions and now I have a stuck bolt with a bigger round hole in it that still won't grip onto the extractor.

I may end up trying to use my die grinder to make a slot to try and screw it out. Or maybe I'll bite the bullet and bring it to my local LBS... I'm swaying towards the LBS because I'm afraid I'll damage it beyond repair.

If they have to drill out the bolt and the riv-nut can a new one be installed in a CF frame? Please tell me yes! I'm thinking worst-case scenario if it comes down to that.

Thanks for everyone's suggestions!
