The front sprockets RFX Pro Series Black Zinc are CNC machined according to the strictest tolerances from high-strength steel and case-hardened to 60 Rockwell degrees to resist wear and ensure their longevity.
The Pro series sprockets also have lightweight holes, if needed, and mud evacuation grooves on both sides to resist dirt buildup and extend the life of the sprocket and the transmission chain.
The front sprocket RFX Pro comes with a black zinc finish that helps combat light corrosion (rust) caused by washing the bike compared to bare plated sprockets and gives an original look.
