A set of 6 HD variator rollers. Outer Diameter: 16mm Depth: 13mm Weight: 6.3 grams (per roller) HD Variator rollers are some of the best available on the market and perfect for replacing stock worn rollers or for tuning purposes. The inner ring is knurled during production to ensure that the outer HD Polymer ring stays in place even during the most demanding applications. The high proportion of PTFE (polytetrafluoroethylene) in the outer jacket provides good self-lubrication and therefore a long service life. The sliding properties of PTFE also ensure a ease of movement during operation. Very good value for money and one of the most resistant variator rollers on the market. You should research in what weight is best for your needs as simply going for the lightest or heaviest weight is not always the best option.
