The patent-pending Redshift ShockStop Endurance suspension seat post (Redshift's original seat post) delivers 35mm of tunable, ultra-responsive travel to smooth out rough terrain and maximize comfort. Ride farther, faster, and more comfortably on the bike you already own, while the ShockStop Endurance Suspension seat post lets you float over chatter, bumps, and broken surfaces with ease.
- Ride farther & more often - the Redshift ShockStop Endurance seat post reduces fatigue from bumps and vibrations with superior shock absorption.
- Ride faster & reduce fatigue - energy that is normally wasted suspending your body is converted into forward motion.
- Better performance & complete control - customize your suspension seat post feel to float over obstacles and maintain traction and control.
