The variator rollers are among the best on the market and are ideal for replacing worn rollers or for tuning. The inner ring is rolled during production to ensure that the HD Polymer outer ring stays in place even under the most difficult conditions. The high proportion of PTFE (polytetrafluoroethylene) in the outer shell ensures good self-lubrication and therefore a long service life. The sliding properties of PTFE also ensure easy movement during operation. Very good value for money and one of the most durable variator rollers on the market.
