Rear Hub (Freehub) Maintenance Notes
Grease lubricates the components that rub against one another in the freehub mechanism of the rear hub, helping reduce friction and wear. Removing all the grease solely to obtain a louder sound is not recommended. Without adequate lubrication, components may wear out or become damaged more quickly, shortening their service life. Use the type and amount of lubricant recommended for product maintenance.
