How to Set Sag on a Mountain Bike

Mountain biking is an exhilarating sport that requires not only physical fitness but also a well-maintained bike. One crucial aspect of bike setup is ensuring the correct suspension sag. Setting sag on a mountain bike is essential for optimal performance and comfort. In this article, we will guide you through the process of how to set sag on a mountain bike.

Understanding Suspension Sag

Suspension sag refers to the amount of travel the suspension has when the bike is fully loaded with the rider and gear. It is crucial to find the right balance between too much sag and too little sag. Too much sag can lead to increased friction and decreased responsiveness, while too little sag can result in harsh impacts and increased rider fatigue.

Tools and Equipment Needed

Before setting sag on your mountain bike, gather the following tools and equipment:

– Bike stand or phone mount
– Digital scale or bathroom scale
– Measuring tape
– Shock pump
– Bike computer or GPS device (optional)

Step-by-Step Guide to Set Sag on a Mountain Bike

1.

Empty the Bike

Start by removing any accessories, water bottles, and gear from the bike. This ensures that the bike is as close to its riding weight as possible.

2.

Mount the Bike on a Stand

Use a bike stand or phone mount to securely attach your bike. This will prevent it from moving while you adjust the suspension.

3.

Measure the Suspension Travel

With the bike mounted on the stand, measure the suspension travel. This is the distance the suspension moves from its fully extended position to its fully compressed position. Most mountain bikes have a travel range of 100-160mm.

4.

Calculate the Target Sag

The target sag is typically between 20-30% of the suspension travel. For example, if your bike has 120mm of travel, the target sag would be 24-36mm.

5.

Adjust the Air Pressure

To achieve the target sag, adjust the air pressure in the shock absorber. Decrease the air pressure if the sag is too high, and increase it if the sag is too low. Use a shock pump to make precise adjustments.

6.

Re-measure the Sag

After adjusting the air pressure, re-measure the suspension sag to ensure it is within the target range. Repeat steps 5 and 6 until the desired sag is achieved.

7.

Check for Uneven Sag

Ensure that the sag is consistent on both sides of the bike. If there is a noticeable difference, adjust the air pressure accordingly.

8.

Re-test the Bike

Once the sag is set, take the bike for a test ride to ensure that the suspension is performing as expected. Make any necessary adjustments to fine-tune the setup.
