No idea what kind of plastics or polymer the pieces are made out of, but they seem durable.Pretty much fixed the noise issue on the pulley, but I think it is a combination of new sliders and rollers (KN Panning 7g set).No issue with installation. Just make sure you have the OEM plate for Vino 50 2T because I tried intalling this on the Jog 50's and it didn't work.WeBike shipped this fast, took just days compared to some items I ordered from big online shops during the holidays.
