Please note that it is extremely difficult to access the Threaded Preload Adjuster on this model. Therefore, it is HIGHLY recommended that this product be purchased with the Hydraulic Preload Adjuster option. The Threaded Preload Adjuster is designed for the rider whose loads do not change and therefore seldom needs to adjust the spring tension on the rear shock.
