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!). Rollers and sliders should be inspected annually (at minimum) for wear. Rollers are especially prone to developing flat spots that inhibit their ability to move smoothly. If this occurs, they should be replaced. This is one advantage of sliders, as they already have flat sides and are not affected by this wear as much as rollers.
