SuperSprox Steel Rear Sprocket
For demanding riders on high powered race machinery, lightweight steel sprockets represent an ideal combination of longevity and performance. SuperSprox steel sprockets feature thicker teeth than comparable sprockets, resulting in greater component life and better engagement with the drive chain.
One of the many tricks up this steel sprocket's sleeve is SuperSprox's Tri-Zinc coating technology that utilizes three distinct coatings for a trifecta of high performance, longevity and good looks. First, the sprocket 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.
