Introduction
The REDSHIFT ShockStop Suspension Seatpost is designed to enhance cycling comfort and control by absorbing road bumps, shocks, and vibrations. This system provides 35mm of tunable suspension travel, allowing riders to maintain consistent power output and reduce fatigue on various terrains. This manual provides essential information for the proper installation, adjustment, operation, and maintenance of your ShockStop Suspension Seatpost.
Safety Information
- Always ensure the seatpost is securely installed and tightened to the manufacturer's recommended torque specifications for both the seatpost clamp and saddle clamp.
- Do not exceed the minimum insertion line marked on the seatpost. Insufficient insertion can lead to frame or seatpost damage and potential injury.
- Regularly inspect the seatpost for any signs of damage, cracks, or wear. Discontinue use immediately if any damage is found.
- Ensure that the saddle angle is correctly adjusted for your riding style after installation to prevent discomfort or injury.
- If you are unsure about any installation or adjustment procedures, consult a professional bicycle mechanic.

Setup
1. Installation
To install the ShockStop Suspension Seatpost:
- Remove your existing seatpost from your bicycle frame.
- Clean the inside of the seat tube and the exterior of the new seatpost.
- Apply a thin layer of carbon assembly paste (for carbon frames/seatposts) or grease (for aluminum frames/seatposts) to the insertion area of the ShockStop seatpost.
- Insert the ShockStop seatpost into the bicycle's seat tube, ensuring it is inserted beyond the minimum insertion line.
- Tighten your bicycle's seatpost clamp to the manufacturer's recommended torque specification.
- Attach your saddle to the seatpost clamp. Adjust the saddle angle and fore/aft position as desired, then tighten the saddle clamp bolts to the recommended torque.

The ShockStop seatpost is available in various diameters (e.g., 27.2mm, 30.4mm, 30.9mm, 31.6mm). If your bike's seat tube diameter is different, shims are available to ensure a proper fit. Always use the correct diameter seatpost or an appropriate shim.

2. Initial Adjustment (Spring & Preload)
The ShockStop seatpost features swappable springs and adjustable preload to customize the suspension feel for your weight and riding preferences.

- Spring Swapping: The seatpost comes with different springs to accommodate various rider weights. Refer to the included spring chart (if provided) to select the appropriate spring combination for your body weight. This typically involves disassembling the lower part of the seatpost to access and replace the springs.
- Preload Adjustment: The preload adjustment knob, usually located at the bottom of the seatpost, allows for fine-tuning the initial stiffness of the suspension. Turning the knob clockwise increases preload, making the suspension firmer, while turning it counter-clockwise reduces preload, making it softer. Adjust this to achieve your desired ride feel.
Operating the Suspension Seatpost
Once installed and adjusted, the ShockStop Suspension Seatpost operates automatically, providing 35mm of active suspension travel to absorb impacts from the road or trail. The optimized linkage geometry ensures that your saddle angle remains consistent throughout the suspension travel, maintaining a stable and comfortable riding position.

This seatpost is suitable for a wide range of bicycles, including road, gravel, hybrid, and e-bikes, enhancing comfort and control across various riding conditions.

Maintenance
The ShockStop Suspension Seatpost is designed for minimal maintenance. However, regular inspection and basic care will ensure its longevity and optimal performance:
- Cleaning: Wipe down the seatpost regularly with a damp cloth to remove dirt and grime. Avoid using harsh chemicals or high-pressure washers directly on the suspension mechanism.
- Inspection: Periodically check all bolts for proper tightness, especially the saddle clamp bolts and any bolts related to the suspension linkage. Inspect the seatpost body for any signs of wear, scratches, or damage.
- Lubrication: The internal mechanism is generally maintenance-free. If you notice any squeaking or unusual noises, consult the manufacturer's website or a professional mechanic for guidance on appropriate lubrication points.
- Mud Guard: The seatpost includes a removable mud guard. Ensure it is clean and properly installed to protect the internal components from debris.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Excessive movement or "bobbing" | Insufficient preload or incorrect spring for rider weight. | Increase preload by turning the adjustment knob clockwise. If still too soft, consider swapping to a firmer spring. |
| Suspension feels too stiff | Too much preload or incorrect spring for rider weight. | Decrease preload by turning the adjustment knob counter-clockwise. If still too stiff, consider swapping to a softer spring. |
| Squeaking or creaking noises | Loose bolts, dirt in mechanism, or lack of lubrication. | Check all bolts for proper torque. Clean the seatpost thoroughly. Consult Redshift Sports for lubrication recommendations if needed. |
| Saddle angle changes during riding | Saddle clamp bolts are not tightened sufficiently. | Ensure saddle clamp bolts are tightened to the recommended torque specifications. |
