Rollers -DR PULLEY (SR-Black Pearl) 21x17mm- 9.5g

Pulley sliding rollers provide significantly better acceleration behavior than normal vario weights. They are precisely manufactured from a special nylon material, which is characterized by particularly good sliding properties on aluminum (the material of the variator). Abrasion is minimal and the one-sided flattening feared with standard rollers is not possible. In contrast to normal variator rollers, Pulley sliding rollers have a service life that is up to 15 times longer.

The weight of the sliding roller should be selected about 10-15% below the weight of the standard roller. This results in much more powerful acceleration with virtually unchanged top speed and fuel consumption. If the weight is selected equal to the original weight, the acceleration will be slightly stronger, but the top speed may increase slightly with the same or even slightly reduced consumption.

NOTE: The correct installation position: The open side of the roller points clockwise to the left.
