I do not have a Zipp CF seatpost.
I do not like Zipp Service Course SL and similar seat posts with an alloy head inserted into a CF tube.
Zipp Service Course SL Seatpost Excel Sports | Shop Online From Boulder Colorado. While I am sure they work just fine, it is worth it to me (at 90 kg) to eliminate another potential point of failure. I prefer seat posts where the surface (on which the bottom saddle rail clamp sits) and the post is formed as a single contiguous CF structure, e.g., Cannondale Save (I have two), Syntace P6 Hiflex (I have one), or Ritchey WCS (I almost ordered one). I also dislike seat posts (Basso, Enve, Easton, etc.) with a single bolt through two side saddle rail clamps, which require different clamps for CF saddle rails, and offer less support than a bottom saddle rail clamp.
I would gladly pay the $135 difference to ride with one less thing to wonder about.
You are hardly the first person to posit that a carbon fiber production facility is a natural monopoly. But I don't think so.

You have a beautiful Time frame. Put proper components on it. Don't be the dude driving an expensive German sedan with mismatched knock off tires.
