4. Setup

4.1. Installation

The ShockStop Suspension Seatpost is designed for easy installation. Ensure your bike's seat tube diameter matches the seatpost (27.2mm). Shims are available separately for larger seat tube sizes.

1. Remove your existing seatpost from the bicycle frame.
2. Clean the inside of the bicycle's seat tube and apply a thin layer of grease if recommended by your bike manufacturer.
3. Insert the ShockStop Seatpost into the seat tube, ensuring it meets the minimum insertion requirements marked on the seatpost.
4. Secure the seatpost clamp on your bicycle frame to the recommended torque.
5. Attach your saddle to the seatpost's adjustable clamp. The two-bolt design allows for precise saddle angle adjustment. Tighten the bolts evenly to secure the saddle.

4.2. Adjusting Suspension

The ShockStop Seatpost offers 35mm of tunable suspension travel to match your riding style and body weight. Adjustments involve swapping springs and fine-tuning the preload.

Refer to the included spring guide or the manufacturer's website for recommended spring combinations based on rider weight. To change springs or adjust preload, the seatpost typically needs to be removed from the bike.

5. Operating

Once installed and adjusted, the ShockStop Suspension Seatpost operates automatically, reacting to bumps and vibrations to provide a smoother, more comfortable ride. The optimized four-bar linkage ensures that your saddle angle remains consistent throughout the suspension travel, maintaining pedaling efficiency.
