The Ritchey WCS 1-Bolt Zero is a seatpost with an extremely clean design and zero offset, ideal for riders who prefer a more aggressive, more over-the-center position on the bike. The wide saddle collar with SideBinder evenly distributes pressure on the rails and protects them, while the single side screw connection allows for quick and precise adjustment of the saddle's position and inclination. The high-quality 7050 aluminum alloy delivers high stiffness at low weight, making this seatpost one of the most functional and aesthetically pleasing models in the Ritchey range.

  • Patented SideBinder lock with one side screw connection for quick saddle adjustment
  • Zero offset suitable for sitting more above the center of the bike
  • The wide contact surface of the lock protects the saddle rails and reduces their strain
  • 7050 aluminum alloy for high rigidity at low weight
  • Clamp for standard 7x7 mm rails with the possibility of replacing them with clamps for carbon rails
