Carbon Rails + Cervelo Seat post= no fit	Can't Post

Anybody else have issue with carbon railed seat not fitting (too fat) on Cervelo P3/P4 seatposts. Have a Kit Carbonio flow that will not fit. Any solutions out there?

problem is, the rail are oval and not round. So those saddles wont fit on p2 p3 p4 seat post clamp. Same with italia optima and other selle italia carbon oval rail.

I have a carbon railed Fizik and I've been using it on my P3 for over a year. I enlarged the slots on the seat tube clamp with a dremel tool since the carbon rails are larger. It might take more than one grinder bit since they tend to wear down before you get the slot large enough.
