• Zip tie or cable tie (to mark the shock stroke)
• Wrench or Allen tool (if necessary to adjust mounting hardware)

Step-by-Step Guide to Rear Shock Sag Setup

1. Check the Manufacturer’s Recommended Sag Range

Before making any adjustments, refer to the manufacturer’s specifications for the recommended sag range for your weight and riding style. For the H3C Trunnion rear shock, this is typically around 25-30% of the total shock stroke. This can vary slightly based on your preference and riding conditions.

2. Set Your Shock Pressure

• First, use a shock pump to set the shock pressure. The recommended air pressure for your weight can usually be found in the user manual or on the shock itself.
• Attach the shock pump to the valve on the shock, making sure the pump is securely connected to avoid air leakage.
• Pump the shock to the recommended pressure, based on your weight. For example, if you weigh 180 lbs, a typical starting pressure could be between 180-200 psi. However, always refer to the specific chart for your shock model to ensure you’re within the correct range.

3. Prepare for Measuring Sag

• To measure sag, you need to compress the shock with your weight. Mount the bike on a stable surface (e.g., a work stand) to keep it upright while you make adjustments.
• Place a zip tie or cable tie around the shock shaft. This will allow you to measure how much the shock compresses when you sit on the bike.

4. Sit on the Bike and Measure the Sag

• Put on all your riding gear, including a helmet, and take your normal riding position on the bike.
• While keeping the bike stable, compress the shock with your body weight. The zip tie will move up the shock shaft as the shock compresses.
• After standing up, carefully check the position of the zip tie to see how much the shock has compressed.
• Measure the distance between the shock’s fully extended position and the zip tie. This distance will give you the sag.

5. Adjust Air Pressure to Achieve the Correct Sag

• Based on your measurements, if the sag is too little (i.e., the shock hasn’t compressed enough), you’ll need to lower the air pressure in the shock.
• If the sag is too much (i.e., the shock compresses too far), increase the air pressure slightly.
• Recheck the sag after adjusting the air pressure and repeat the process until the correct sag is achieved (typically 25-30% of the shock stroke).

6. Fine-Tune the Setup

Once you’ve set the initial sag, test the bike in various riding conditions. If the bike feels too stiff or too soft, adjust the pressure slightly until the suspension feels right. Keep in mind that you might need to make minor adjustments after a few rides as the shock settles in or changes in weather conditions occur.
