Seatpost Rack Is There A Good Seatpost Rack For Carbon Fiber Seatposts? Is This Even Possible Or A Good Idea?

Is there a good seatpost rack for carbon fiber seatposts? Is this even possible or a good idea? - seatpost rack

I have a bicycle seat post world, with carbon. Last year I bought a MTX beamrack and now read that I do not even want to use seatpost with carbon fiber.

Is there a plateau that I can use? I want to be able to things with me sometimes (but not carry a lot ...)

I am a newcomer to cycling, so forgive my ignorance!
