Vortex 824CZB-50 Aluminum Rear Sprocket 50-Tooth Black Anodized

The Vortex 824CZB-50 is a 50-tooth aluminum rear sprocket finished in a corrosion-resistant black anodized coating. Engineered for street and track riders who demand lightweight performance without sacrificing durability, this sprocket is 100% CNC machined in the USA from a specially formulated aluminum alloy developed to Vortex's own specifications.

Vortex's patented tooth geometry sets this sprocket apart from the competition. The unique profile reduces wear on both the sprocket and chain, extending the service life of your entire drivetrain. The black anodized finish not only resists corrosion but gives the sprocket a clean, aggressive appearance on the bike.
