Setup and Installation
Proper installation and setup are crucial for optimal performance and safety. The ShockStop Suspension Stem is designed for straightforward installation.
Compatibility
- Fits standard 1-1/8 inch (28.6 mm) steerer tubes.
- Compatible with 31.8 mm handlebars. Shims may be available for 25.4 mm and 26.0 mm handlebars (check manufacturer's website for details).
- The 55 mm and 70 mm stem lengths are specifically compatible with drop handlebars only.

Elastomer Selection and Tuning
The stem includes 5 swappable elastomers, allowing you to fine-tune the stiffness and feel of the suspension to match your riding style and weight. Refer to the manufacturer's guidelines for recommended elastomer combinations based on rider weight and desired ride characteristics.

Stem Angle and Length Options
The ShockStop stem is available in various lengths and angles to suit different bike geometries and rider preferences. The current model is 55mm length with a 6-degree angle. Other options include:
- +6 degree with 55 mm, 70 mm lengths.
- Flippable +/-6 degree in 80, 90, 100, 110, and 120 mm lengths.
- +30 degree in 80 and 100 mm lengths.

Operating Principles and Benefits
The ShockStop Suspension Stem provides up to 20mm of damped suspension travel at the handlebars, significantly improving ride comfort and control.
Vibration Dampening and Fatigue Reduction
This stem is engineered to reduce the effects of impacts and vibrations by up to 70%. By absorbing these forces, it helps alleviate common discomforts such as sore hands, wrists, back, and neck, which are often experienced during long rides or on rough terrain. This reduction in physical strain allows riders to maintain energy and ride further and faster.

Enhanced Control and Stability
Despite offering suspension, the ShockStop stem maintains the lateral rigidity of a standard stem. This ensures that steering responsiveness and control are not compromised, providing confidence during high-energy activities like sprinting or climbing out of the saddle. Riders can float over obstacles while maintaining precise handling.

Maintenance
The REDSHIFT ShockStop Suspension Stem is designed to be low-maintenance. Regular cleaning and inspection are recommended to ensure longevity and optimal performance.
- Cleaning: Wipe down the stem regularly with a damp cloth to remove dirt and grime. Avoid using harsh chemicals that could damage the finish or internal components.
- Inspection: Periodically check all bolts for proper torque, especially the handlebar clamp and steerer tube clamp bolts. Ensure the elastomers are seated correctly and show no signs of excessive wear or damage.
- Elastomer Replacement: While durable, elastomers may degrade over time or with heavy use. If you notice a change in suspension performance or visible wear, consult the manufacturer's website for replacement elastomers and instructions.
Troubleshooting
If you encounter issues with your ShockStop Suspension Stem, consider the following common solutions:
- Stem feels too stiff or too soft: This is typically related to elastomer selection. Re-evaluate your elastomer combination based on your weight and riding preferences. Ensure the correct elastomers are installed according to the manufacturer's guide.
- Unusual noises or creaking: Check all bolted connections, including the handlebar clamp, steerer tube clamp, and any internal stem bolts. Ensure they are torqued to the manufacturer's specifications. A small amount of grease on bolt threads (where appropriate) can sometimes resolve creaking.
- Reduced suspension travel: Verify that the elastomers are not compressed or damaged. Ensure no foreign objects are obstructing the stem's movement.
- Handlebars slipping: Ensure the handlebar clamp bolts are tightened to the specified torque. Clean the handlebar and stem clamp surfaces to remove any grease or dirt that could reduce friction.
