ZF Gold Dual Rear Sprocket 428 – 60 Teeth

ZF Dual Sprockets are among the highest quality and most technically advanced sprockets in the world.

The secret is based on the combination of durable steel and the lightness of duralumin, a strong, hard and lightweight alloy of aluminium.

• The tensile strength is around 11 times that of pure aluminium.
• Through the curing process, duralumin almost reaches the strength of steel.
• Milling of the tooth base of the sprocket guarantees optimal self-cleaning.
• These cuts ensure that the dirt can not get between the teeth and prematurely wear the chain and the sprocket
• The durability of the ZF-Dual sprockets is around three times longer than pure aluminium sprockets and 50% lighter than steel.
• Made from the best quality German aluminium supplied by World Leading supplier. Used by Airbus, Boeing & Audi.
• ISO Certified Standard Aluminium ISO 7075 T6
