Vortex 436ZB-48 CAT5 Rear Aluminum Sprocket 530 Pitch 48-Tooth Blue

The Vortex 436ZB-48 is a CAT5 rear aluminum sprocket featuring a 530 chain pitch and 48 teeth, finished in a striking blue anodized color with contrasting silver machine-cut highlights. Designed for performance-minded riders, this sprocket is a lightweight, high-quality upgrade over stock steel units.

Vortex's CAT5 sprockets utilize a distinctive color anodizing process applied before CNC machining, which excludes the sweeps, mud grooves, and teeth — resulting in a vivid color with bright silver accents. The sprocket is manufactured entirely in the USA from a specially formulated aluminum alloy developed to Vortex's own exacting specifications.
