Select weight sizes now available in Black Pearl material: 10g, 11g, 13.5g, 14g. Traditionally, gear ratio is changed by the up-and-down rolling movement of the roller weights in the ramp of the Moveable Drive Pulley (MDF). Now the innovative Dr. Pulley Sliding Roller Weights slide up-and-down the ramp to change the gear ratio. This unique sliding movement (not rolling) provides exclusive advantages to increase CVT performance. With Dr. Pulley, no abnormal wear will occur even when running in high gear. Please see our Warranty & Returns Policy.

Sliders by Design never work well they're incredibly inconsistent with variation regardless of the weight
