I have a new saddle and I want to buy a compatible seatpost. The saddle rails is
CARBON 7x9 as specified by the manifacturer.
I want to understand better the compatibility of this kind of oval rails. Some seatpost manifacturers specify compatibility, here is an example:
Rail Compatibility Round and Square Rails
However, in most other cases, the compatibility is not specified.
Should I assume 7x9 is compatible by default with any seatpost or not?
This seems to suggest that there is some difference between the clamps I have to pick.
