How to Set Sag on a Mountain Bike

Setting sag on a mountain bike is an essential skill for any rider looking to optimize their suspension performance. Sag refers to the amount of travel that the suspension has when the bike is fully loaded and riding. Proper sag ensures that the suspension is working effectively, providing a smooth and comfortable ride. Here’s a step-by-step guide on how to set sag on a mountain bike.

1. Weigh Your Bike: First, weigh your bike with all the necessary gear on it, including water bottles, tools, and any other items you carry. This will give you an accurate weight to use for setting sag.

2. Find the Right Sag Percentage: The ideal sag percentage for most mountain bikes is between 20% to 25% of the total suspension travel. This range can vary depending on the type of riding you do, but it’s a good starting point.

3. Adjust the Air Pressure: Begin by adjusting the air pressure in your shock to the recommended setting. This is usually found in the shock’s manual or on the shock itself. Then, slowly decrease the air pressure until you reach the desired sag percentage.

4. Check the Sag: To check the sag, place your bike on a flat surface and measure the distance from the ground to the bottom of the shock. Then, ride the bike until it’s fully loaded and measure the distance again. Subtract the unloaded measurement from the loaded measurement to find the sag.

5. Adjust as Needed: If the sag is not within the desired range, adjust the air pressure accordingly. If the sag is too low, increase the air pressure. If the sag is too high, decrease the air pressure.

6. Check the Lockout: If your shock has a lockout feature, ensure it’s properly adjusted. For most riders, the lockout should be engaged when the bike is climbing and disengaged when descending.

7. Fine-Tune the Rebound: Once you have the sag set, adjust the rebound damping to ensure the suspension is working smoothly. The rebound should be fast enough to allow the suspension to move freely but not so fast that it bounces around.

8. Test Ride: After making adjustments, take your bike for a test ride to ensure everything is working as intended. Pay attention to how the bike feels over different types of terrain and make any necessary adjustments.

By following these steps, you can effectively set sag on your mountain bike and enjoy a more comfortable and efficient ride. Remember, the key is to find the balance between too much sag and too little sag, as both can lead to poor suspension performance.
