I have a 2015 Specialized Roubaix SL4 Disc with a CG-R seatpost, and recently bought a Fizik Vento Argo R1 short-nose saddle for it.

Knowing it has ovalised carbon rails and not the standard 7 mm alloy rails, I ordered a different clamp for 7x9mm rails. I was dismayed to discover, however, that the Vento Argo R1 actually has 7x10mm rails.

Will this work? Is it safe? Is there another clamp I can put on a CG-R seat-post which is specifically meant for the rails on the Fizik saddle?
