The patent-pending Redshift ShockStop PRO Race Suspension seat post delivers true race-tuned performance while cutting up to 130g compared to the original ShockStop Endurance post. Its hybrid suspension pairs coil springs with elastomers to blend rapid response to bumps and vibration with a refined, low-profile feel that lets you keep power smooth and steady. Rider-adjustable stiffness makes it easy to fine-tune the setup to your preferred feedback and riding style. Being more comfort in the saddle means youâll be able to ride longer, go faster, and maintain control even on the roughest terrain. The minimal, lightweight design of the ShockStop PRO Race Suspension seat post blends seamlessly with the aesthetic of modern gravel and road bikes.Â
- Race-tuned - the combination of coil springs and elastomers provides a progressive spring rate that lets the suspension work effortlessly to absorb the bumps and buzz of gravel or road riding, while still providing a firm foundation to maximize power delivered to the pedals. The PRO Race seatpost disappears into the background, letting you stay in control and focused, while leaving you less fatigued after every ride.
- PRO Level - up to 25% weight reduction (130 grams!) from original ShockStop Endurance Seatpost and ultra-sleek styling
- Go farther - reducing fatigue from bumps and vibrations
- Ride faster - energy that is normally wasted suspending your body is converted into forward motion
- Improve control - float over obstacles
- For the ultimate suspension system, pair with the ShockStop PRO Stem or ShockStop Stem
