Vortex 435ZR-48 CAT5 Red 48-Tooth 520-Pitch Aluminum Rear Sprocket

The Vortex 435ZR-48 is a lightweight CAT5 anodized aluminum rear sprocket featuring 48 teeth and a 520 pitch. Engineered as a high-performance upgrade over heavy steel OEM sprockets, this sprocket is 100% CNC manufactured in the USA from a specially formulated aluminum alloy per Vortex specifications — delivering an exceptional combination of strength and reduced rotating mass.

The CAT5 color anodizing process is applied to the face of the sprocket while leaving contrasting silver machine cuts on the sweeps, mud grooves, and teeth, resulting in a bold red finish with bright silver highlights. The electrically coated surface provides a brighter shine while helping resist corrosion.
