The SuperLogic 1-Bolt Seatpost featuring FlexLogic technology brings together simplicity and function in Ritchey's lightest seatpost design. The patented SideBinder clamp uses a single 5mm side bolt that keeps the wide clamp securely fastened while reducing stress on lightweight saddle rails. FlexLogic offers more vibration damping than standard carbon posts due to unique carbon layup methods that provide outstanding performance during longer rides. The SuperLogic 1-Bolt Seatpost features a precision forged alloy clamp for strength, while its low-profile head delivers optimal saddle clearance and sleek lines. Interchangeable clamps provide compatibility for all popular rail sizes.
