20g 20×15 Sliding Roller Counterweight

Description

Here is an excellent bargain. The 20 gram 20×15 Dr. Pulley sliding roller weight is priced to sell. But if you want this pack of six roller weights you had better act fast.
Traditionally, the gear ratio in scooter CVTs is changed by the in-and-out rolling movement of the roller weights. With the innovative Dr. Pulley sliding roller weights, the roller weights “slide” inward and outward in the Movable Drive Pulley (MDF) to change/extend the gear ratio.
