Redshift ShockStop Suspension Stem for Gravel, Road, & MTB Bikes
SKU:
SHOCKSTOP SUSPENSION STEM
The patented ShockStop Suspension Stem smooths out road imperfections, reducing fatigue and strain. Whether you're on a local group ride, or exploring gravel back roads, the ShockStop Stem will make your ride smoother, faster, and more comfortable.
The minimal design of the ShockStop Stem blends seamlessly with the aesthetic of modern bikes, while reducing fatigue and strain. Along with the ShockStop Suspension Seatpost, this system works together to suspend the rider and smooth out rough terrain on the bike you already own, making your ride smoother, faster, and more comfortable. Great for bikepacking, gravel biking and commuter e-bikes.
Benefits of a Suspension Stem:
- Go further - reduce fatigue from bumps and vibrations
- Ride faster - energy that is normally wasted suspending your body is converted into forward motion
- Take control - customize your suspension feel to float over obstacles and maintain control over rough terrain
