Specifications:
- ZF dual pinions are among the highest quality and most technologically advanced pinions in the world;
- based on the combination of steel strength and aluminum lightness;
- this aluminum alloy is characterized by enormous strength and tightness as well as low weight;
- tensile strength is approximately 11 times that of pure aluminum;
- through the hardening of duralumin, it has nearly reached steel strength;
- implemented, therefore, is a lower weight and greater durability;
- based on the tooth of the chain wheel ensures optimal self-cleaning;
- ensures that dirt cannot fit between the teeth and, therefore, does not age the chain and sprocket so quickly;
- the durability of the dual IF pinions is approximately three times greater than that of pure aluminum pinions and they are 50% lighter than steel pinions;
- ideal for road and off-road;
