The design changes include moving from the single pawl of the 36 tooth design to the patented dual pawl of the 72 tooth design.The dual pawl 72 tooth design utilizes a single spring.We took four years of testing to perfect the low spring pressure needed to maintain Ko-ken’s hallmark low-torque backlash.The finer 72 teeth design creates more surface area contact with the gear; thus, it has a 10% higher torque upper limit
