Product Name: REAR SPROCKET DUAL 51 TOOTH PITCH 520 RED
The ZF Dual Sprocket offers exceptional quality and advanced technology, making it one of the premier sprockets available. Crafted from a high-strength duralumin alloy, this sprocket ensures a remarkable blend of durability and lightweight performance. With a tensile strength approximately 11 times that of pure aluminum, it delivers outstanding resistance and longevity.
Through a unique hardening process, the strength of duralumin approaches that of steel, allowing for reduced weight while enhancing durability. The milled grooves in the tooth base provide optimal self-cleaning, preventing dirt accumulation which minimizes wear on both the chain and sprocket.
The longevity of ZF Dual sprockets is estimated to be three times greater than standard aluminum variants, while being 50% lighter than steel options, making them perfect for various riding conditions, whether on the road or off-road.
