The Williams Impact ACS seatpost is designed for high strength, low weight, and efficient use of every gram.  The shaft and head are not bonded but are 3D-forged from a single piece of 7014-T6 aluminum.  The Impact ACS seatpost is available in 350 mm length as well as 27.2 mm and 31.6 mm diameters.

We set out to create a seatpost with a competitively low weight and unparalleled durability and ease of use. We use 7050 alloy clamping hardware for bulletproof durability. The strength and weight of this seatpost are exciting, but it's the design that makes it a cut above. The clamp utilizes a two bolt system.  And, the 2 bolt clamp is designed to work flawlessly with Williams SLC carbon rail saddles.

The whole package is black anodized, making for a stunning appearance. Light weight, massive strength, and great functionality make the Impact ACS the obvious choice for anyone looking to upgrade to the highest seatpost technology.
