Dual crown 520 40 teeth gold LTZ 400 DVX 400 KFX 400

ZF crown gears are among the highest quality and most technologically advanced gears in the world.

The secret lies in the combination of the strength of steel and the ease of use of duralumin.

This aluminum alloy is characterized by enormous strength and rigidity, as well as light weight.

The tensile strength is approximately 11 times that of pure aluminum.

Through hardening, duralumin almost achieves the strength of steel.

It has therefore implemented a lower weight and greater durability.

Grinding at the base of the chain wheel tooth ensures optimal self-cleaning.

These millings ensure that dirt cannot get between the teeth and therefore the chain and sprocket do not wear out as quickly.

The durability of IF double sprockets is approximately three times that of pure aluminum sprockets and they are 50% lighter than steel sprockets.

Ideal for on-road and off-road use.
