This 20 tooth 8mm REX™ bore pinion gear is ready to rip! The bore perfectly matches our 8mm REX™ shafting to create a positive drive. While little work is left for the set screws, we put two of them in for good measure. This particular gear is most commonly mated to a 100 tooth hub gear in order to create a 5:1 ratio however if your build provides the freedom to adjust the spacing between your gears, it’s able to mesh to any MOD 0.8 gear that suits your fancy.
