Redshift Shockstop City Suspension Seatpost

The patent-pending ShockStop City Suspension Seatpost provides 35 mm of tunable, ultra-responsive suspension travel for the ultimate bump-eating comfort. Designed specifically for e-bikes, commuting and city riding to help you ride farther, faster, and more comfortably on the bike you already own.

The ShockStop lineup of suspension seatposts feature a proprietary parallelogram design, which allows for the suspension to remain active even when you're seated and pedaling. This means that you can benefit from the suspension's smoothing effect even when you're putting down power, unlike some suspension seatposts that become rigid when you're pedaling.

Features:

• More comfort , less fatigue - the ShockStop City Seatpost smooths out your ride and reduces fatigue from bumps and vibrations with superior shock absorption
• Better performance & complete control - customize your suspension seatpost feel to float over obstacles and maintain traction and control
• Ride faster & farther - energy that is normally wasted suspending your body over bumps, cracks and potholes is converted into forward motion
• 35 mm of active suspension travel optimized for e-bikes, commuting, city riding, and recreation
• Optimized linkage geometry provides ultra-responsive suspension feel
• Infinitely adjustable stiffness via pre-load adjustment and swappable springs
