Description
ZF Dual sprockets are among the highest quality and most technically advanced sprockets in the world. The secret is based on the combination of the durability of steel and the lightness of duralumin. This aluminium alloy is characterized by enormous strength and tightness, as well as low weight.
The tensile strength is about 11 times that of pure aluminium. Through hardening, duralumin reaches almost the strength of steel. Consequently, lower weight and higher durability have been achieved.
Millings in the tooth base of the sprocket guarantee optimal self-cleaning. These millings ensure that the dirt can not settle between the teeth and thus the chain and the sprocket do not wear out so quickly.
The durability of the ZF Dual sprockets is about three times longer than pure aluminium sprockets and are 50% lighter than steel sprockets.
