The Williams Ionic CCS seatpost is a triumph of design. We set out to create a seatpost with a competitively low weight and unparalleled durability and ease of use. Many companies pair a carbon fiber post with an alloy head, but not us. We construct both the length of the post and the head with high modulus carbon fiber, which keeps the weight of the seatpost impressively low. But we use 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. This allows you to dial in the angle of your saddle with unrivaled precision. And, the clamp is designed to work flawlessly with Williams SLC carbon rail saddles. The whole package is finished off in a glossy UD carbon, making for a stunning appearance. Light weight, massive strength and great functionality make the Ionic CCS the obvious choice for anyone looking to upgrade to the highest seatpost technology.
