I recently bought a gravel bike that came with Specialized Phenom Expert saddle in 143mm. I've been using Fizik Antares R3 on my road bike but after having a mind-blowing experience with the Phenom, I'm thinking about buying it for my road bike as well. Specialized's low level comp and expert are quite heavy so I was looking at Pro or S-Works models. Specialized website says however that "Oversized 7x9mm carbon rails are not compatible with seatposts equipped with side-load clamp mechanisms for 7mm round rails." (https://www.specialized.com/us/en/pheno ... 234-130635). I'm not sure what to make of this. My seatpost is the same as the one in the attached photo. Do you reckon that would work?
