REDSHIFT ShockStop Suspension Stem for Bicycles - Smooth Ride

Our review of the REDSHIFT ShockStop stem finds it best suited for riders who want a noticeably smoother handlebar feel without sacrificing steering precision. The stem's main appeal is its ability to soak up road and trail vibrations, reducing hand, wrist, and upper-body fatigue so riders can stay comfortable on longer rides. Installation is straightforward for most road, gravel, hybrid, and e-bike frames with a standard 1-1/8 in steerer and 31.8mm bars, and the stem's tunable elastomers let cyclists dial in the firmness they prefer.

Key Features

• Up to 70% vibration dampening: Cuts transmitted bumps and vibrations to the hands and arms, improving comfort on rough surfaces and reducing fatigue over long rides.
• 20mm of damped suspension travel: Provides vertical compliance that smooths sharp impacts while keeping lateral stiffness for confident sprinting and climbing.
• Tunable suspension: Five swappable elastomers allow precise adjustment of stiffness so riders can tune the stem to pavement, gravel, or mixed terrain.
• Maintenance free: Designed to be easy to install and require no ongoing maintenance, making it a practical upgrade for regular cyclists.
• Compatibility: Fits standard 1-1/8 in steerer tubes and 31.8mm handlebars (shims available separately), making it a direct replacement for many road and gravel stems.

Who It's For

The ShockStop is ideal for road, gravel, hybrid, and e-bike riders who routinely encounter rough surfaces and who want to reduce hand and arm fatigue without changing riding position. Cyclists recovering from numbness or shoulder discomfort will appreciate the stem's impact damping and the ability to fine tune feel with elastomers.

It is less suitable for frames with oversized steerer tubes or riders who need an ultra-lightweight race setup where every gram matters; the stem prioritizes comfort and compliance over minimal weight. Riders with nonstandard steerers should look for other solutions compatible with their headset dimensions.
