How can the preload adjustment of a rear shock absorber be done?

To adjust the preload, loosen the lock screw with an Allen wrench. Forcing the preload ring to turn without loosening the lock screw can cause damage to the parts.

- Turning the preload ring clockwise increases the preload, reducing sag.

- Turning the preload ring counterclockwise decreases the preload, increasing sag.

It is recommended to have a sag of approximately 1.5-2 centimeters, which is about one-fourth of the total travel. Once adjusted, lock the lock screw, and the preload ring should not rotate easily. Over-tightening can cause damage to the parts. For dual-suspension bikes, adjust both sides equally.
