The Ergon CF3 isn't cheap but reports are that it really works to absorb vibration.

I believe the Canyon VCLF seatpost is designed similarly. It doesn't look like it will play well with Di2 though.

This can't be stressed enough and is a great point. Another area to look is the saddle.

I own the Fabric Scoop Ultimate Carbon with flexible base and again, thought the rear tire was low the first time I rode it because it was flexing. It helps a lot. People riding behind me have commented that they can see the base flex. I'd be surprised if there were not other brands.

My point is that those concerned with vibration damping might want to look into some of the gravel specific technologies and products out there.
