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.
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.
