Vortex 840AZUV4-40 Aluminum Rear Sprocket 520 Pitch 40-Tooth Silver Anodized

The Vortex 840AZUV4-40 is a lightweight aluminum rear sprocket engineered for riders who demand race-proven performance and precision. Part of Vortex's 840 series designed for aftermarket wheel fitment, this 40-tooth, 520-pitch sprocket is 100% CNC machined in the USA to exacting tolerances, delivering consistent concentricity and long-term durability.

Crafted from a specially formulated aluminum alloy per Vortex's own specifications, the sprocket features a silver anodized finish that resists corrosion while keeping weight to a minimum.
