Dr. Pulley Slide support

on the front variomatic unit
A very good fit with the special polymer nylon material, similar to the Dr. Pulley Vario rollers - prevents high wearing and achieves optimum sliding properties on the mounting plate. No need of additional greases because self-lubricating. They should be exchanged always at the same time with the Vario rollers to achieve a steady wear of the rollers and the slider. Usable for original Dr. Pulley and other variators
