How to Properly Set the Sag on a Mountain Bike for Optimal Performance
Setting the sag on a mountain bike involves adjusting the amount of suspension compression when the rider sits on the bike. First, check the manufacturer’s recommended sag percentage for your bike model and weight. Next, stand on the pedals and note the position of the suspension o-rings or zip ties. Sit on the bike in your normal riding position and have a friend help you measure the o-ring or zip tie position again. If the sag is not within the recommended range, adjust the air pressure or add/remove volume spacers in the fork or shock to achieve the desired sag. Recheck and fine-tune as needed.
