This pulley offers improved traction, especially if added to a setup with a 47mm sports cylinder or higher. The pulley is designed to eliminate dead points in the pull-up, and therefore provides a smoother acceleration curve.
The pulley can be set in two different pitches and used together with the other original or standard pulley.
Note: The pulley requires a setup with a minimum of 70ccm / 47mm sports cylinder to drive optimally. Legal or standard setups can have a hard time towing the pulley.
