By changing the length of the pulley boss located at the center of the pulley, it is possible to move the drive belt further to the outside of the pulley, increasing the maximum speed. Also, depending on the mounting position of the two included shims, detailed acceleration characteristics can be set. A DLC type is also available, which reduces friction loss and prevents wear due to lack of lubrication, achieving stable pulley operation.
