Vortex 436ZB-43 CAT5 Aluminum Rear Sprocket 530-Pitch 43-Tooth Black

The Vortex 436ZB-43 CAT5 Rear Sprocket is a high-performance, lightweight aluminum racing sprocket designed for serious street and track riders. Built from a specially formulated 7075 aluminum alloy per Vortex's own specifications, this sprocket is 100% CNC manufactured in the USA to the tightest tolerances for consistent, reliable performance.
