Vortex 454ZB-41 CAT5 Aluminum Rear Sprocket 525-Pitch 41-Tooth Blue

The Vortex 454ZB-41 is a 41-tooth, 525-pitch rear sprocket machined from lightweight CAT5 aluminum and finished in an anodized blue with contrasting silver machine-cut accents. Designed and manufactured entirely in the USA, this sprocket is built to race-grade standards for riders who demand performance and durability without the weight penalty of steel.

Vortex sprockets are constructed from a specially formulated aluminum alloy developed to Vortex's own specifications, providing an optimal balance of strength and low weight. The body is cupped down from the tooth ring to reduce mass wherever possible, and the teeth are hardened to maintain their profile over thousands of miles without sacrificing structural integrity.
