What kind of seat clamp for carbon rails?

Postby Colin151 » 25 Jul 2020, 1:04am

I have searched but can’t see to find a definite answer
I am interested in buying a saddle with 7 by 9 carbon rails. Like a Specialized or Fizik saddle.
What kind is saddle clamp at the seat post is acceptable. Is only a vertical seat clamp acceptable?(using two bolts) or is it also possible to use a horizontal clamp? I see that trek and bontrager sell 7 by 9 ears for seatposts with horizontal seat clamps?
Or does it only depend on saddle in question. In that case does anyone know if it possible to use both methods of clamping with Specialized and Fizik saddles or not?

Any info would be greatly appreciated.
