Ritchey Superlogic 1-bolt Flexlogic seatpost 2026

The SuperLogic 1-Bolt Seatpost with FlexLogic technology combines simplicity and functionality in Ritchey’s lightest seatpost design. Its patented SideBinder clamp uses a single M6 bolt to securely fasten the precision-forged alloy clamp, which confidently holds the saddle rails within a unique cradle system.
FlexLogic’s unique carbon layup delivers superior vibration damping compared to standard carbon posts, enhancing performance and comfort on longer rides. Interchangeable clamps are available to accommodate all popular rail sizes.

Flexlogic
15% more vertically compliant than other carbon layups, FlexLogic technology offers more compliance, increased versatility, and less weight.

1-bolt Clamp
A simple and elegant design that offers near infinite axial adjustment with just one bolt security.

Force-Directional Butting
Oblong internal shaft diameter - thicker wall where needed for strength, less material where it’s unnecessary.
