Vortex 527ZB-38 CAT5 Rear Aluminum Sprocket 527 Pitch 38-Tooth Blue

The Vortex 527ZB-38 CAT5 Rear Aluminum Sprocket delivers race-proven performance in a lightweight, eye-catching package. Machined from a specially formulated aluminum alloy to Vortex's exacting standards, this 38-tooth, 527-pitch rear sprocket is significantly lighter than comparable OEM steel sprockets, reducing rotating mass for improved acceleration and throttle response.

The striking blue anodized finish covers the sprocket body while the teeth and machine cuts retain a contrasting silver highlight — the result of Vortex's signature color anodizing process that excludes sweeps, mud grooves, and teeth. This gives the sprocket a distinctive two-tone appearance that stands out on the bike.
