More compliance. Zero compromise.
Most carbon seatposts either stay too stiff or go soft and vague. Ritchey’s FlexLogic layup solves that problem.
Developed for Pro Tour teams and refined for real-world road and gravel riding, FlexLogic delivers roughly 15% more vertical compliance than standard carbon constructions — without sacrificing lateral or torsional stiffness. The result is a post that actively damps road buzz and high-frequency vibration while keeping your power transfer clean and direct.
You stay seated longer on rough pavement and light gravel. Your body takes less of a beating over the long haul. And the bike still feels sharp and responsive under hard efforts.
