ZF double sprockets are among the highest quality and most technically advanced sprockets in the world.
The secret lies in the combination of the durability of steel and the lightness of duralumin.
This aluminum alloy is characterized by its enormous resistance and hermeticity, as well as its low weight.
The tensile strength is approximately 11 times that of pure aluminum.
When cured, duralumin nearly reaches the strength of steel.
Consequently, a lower weight and higher resistance have been implemented.
The milling of the tooth base of the toothed wheel ensures optimal self-cleaning.
These cuts ensure that dirt cannot stick between the teeth and thus wear down the chain and sprocket not so quickly.
The durability of ZF-Dual sprockets is approximately three times longer than pure aluminum sprockets and 50% lighter than steel sprockets.
