Dr. Pulley Sliding Roller Weights 20x12 for 300cc
Dr. Pulley slider weight size 20x12. This product comes with eight slider weights in the package. Traditionally, the gear ratio in the CVT 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.
Set of 8
Broadens your range of gear ratios
Increases acceleration and re-acceleration properties

Lasts longer than standard roller weights
U.S. Patent Number: 7,276,004
Dr. Pulley Sliders are a different style of roller and can be used with your stock variator. The unique shape offers a variety of benefits:
--Sliders engage up to 20% faster than traditional rollers. They allow you to engage in higher gear ratios.
--Sliders last longer with much less wear than rollers because they slide rather than roll (hence the name!).
Choosing a slider weight size:
- Lighter roller weights will give more climbing power at the consequence of losing some top end speed.
- Heavier roller weights will allow more top speed at the serious expense of climbing ability - but are great for flat-ground racing.
