The Serpent 802173 aluminium pulley and shim set is built for pilots of the 720-09 GP vintage series. Precision machined and anodised, it provides a lightweight option that helps keep belt teeth cleaner and lowers the frequency of routine cleaning.
With a 22 tooth layout tailored to the Serpent Vintage Series 720-09 200mm GP, this set helps maintain smooth engagement and reduces abrasive wear on belts under normal running conditions. The accurate profile aids consistent power transfer on race day.
