The original Bi-Metal sprocket Supersprox

The inner ring of the Stealth sprocket is constructed from lightweight aluminum with CAD-designed, weight-saving cutouts, minimizing unsprung weight. To ensure longevity and durability, the outer ring is made of much more resilient steel.

Originally designed for the KTM Dakar Rally Race Team, the SuperSprox Stealth Rear Sprocket is the go-to choice when there can be no compromises. While aluminum sprockets are coveted for their lightness, they wear out quickly, especially in rough conditions or on high horsepower machines. Steel sprockets might be durable enough to go the distance, but their comparatively higher weight makes them less than ideal for riders and race teams looking to squeeze every drop of performance from their machinery. The short comings of each material inspired SuperSprox to come up with a hybrid alternative.

The inner ring of the Stealth sprocket is constructed from lightweight aluminum with CAD-designed, weight-saving cutouts, minimizing unsprung weight. To ensure longevity and durability, the outer ring is made of much more resilient steel. Adding to the steel's resilience is SuperSprox's special three-step, Tri-Zinc finishing. First, the steel ring is coated in a mixture of silver and nickle, which fights corrosion. The second step in the coating process is a black passivation that fills the micro pores in the steel's surface, ensuring abrasive rust and road debris aren't able to become lodged in between your drive components for long enough to cause serious damage. Finally, the steel is finished with a slick, smooth top coat that helps keep it clean and looking good for years to come.
