WCS Carbon 1-Bolt Zero Offset Seatpost



The WCS Carbon 1-Bolt seatpost is a masterpiece of Ritchey's design philosophy – creating innovative products that meet Tom's high standards of performance and durability. Whether for a race rig or to finish off a custom build, the Ritchey WCS Carbon 1-Bolt post packs supreme functionality into a deceptively simple design. The key feature of this beautifully efficient seatpost is the single side load bolt that keeps the wide clamp together while reducing stress on the saddle rails – keeping secure the most critical interface on your bike while you rock, roll, and rip your favorite roads, trails, or paths.
