Zipp's Carbon SL Speed Seatpost has become a favorite of road and cyclocross pros because of its light weight and dependability.
Engineers used SRAM's Exogram™ technology to make the tube as lightweight as possible and optimized the clamping system for adjustability, security, and ease of use.
What's more, the SL Speed is available in a 400mm length to accommodate road bikes with compact frame geometry.
Available in 0mm or 20mm setback options.

Beautiful finish and light weight but: the connecting hardware binding the seatpost cannot be tightened enough. After torquing it up to spec the saddle soon began loosening, which is awfully frustrating. Very quickly it requires a new bolt kit because the metal groove wears down from the slippage. This does not seem like a good mechanism. I've assembled and ridden many bikes through the decades and this is my first seatpost problem. Perhaps I (and Zipp) gave in prematurely to the allure of light weight.
I was hesitant to get a straight seat post without a setback since tests have shown that a setback provides more comfort from the road vibrations. I really couldn't tell the difference between this post and the setback post I had before. So no regrets
Making seat adjustments is easy since you only have one screw to loosen and tighten.
The two things that I have a problem with is the Torx screw head! Why not keep it Hex so I don't have to carry an extra tool. The other thing is...the seat seams to tilt if the screw isn't really tight. I don't have a torque wrench but I did tighten it pretty hard with the wrench they provided...yet the seat still seems to tilt a little when I hit bumps. I'm afraid to break the screw if I tighten it anymore.
