Not sure which bike @
corrado33 is referring to. In either case, I don't see a CF rack in my future.
As far as weight is concerned, think about how much weight your body puts on the seatpost. An additional 10 pounds or so is not going to break it. All attachments are velcro and nylon straps, which help absorb any shock. The only issue with CF is clamping something to it, which puts all the stresses in a small area. Not generally an issue with bikepacking bags, but a seatpost rack on a CF seatpost or a standard rack clamped to CF seatstays is generally not advisable.
