How to Easily Adjust Sag on Your Mountain Bike: A Step-by-Step Guide
To adjust sag on a mountain bike, you need to stand on the pedals in your normal riding position, then have someone measure the sag between the center of the rear axle and the top of the seat. If the sag is too much or too little, adjust the rear shock’s air pressure accordingly, until the sag is at around 25-30% of the total rear suspension travel. Fine-tune the pressure until you find a comfortable and effective setting for your weight and riding style.
