Vortex 485ZR-43 CAT5 Silver Aluminum 43-Tooth 520-Pitch Rear Sprocket

The Vortex 485ZR-43 is a CAT5 aluminum rear sprocket featuring a 43-tooth, 520-pitch configuration with a silver anodized finish. Manufactured 100% in the USA using CNC machining and a specially formulated aluminum alloy per Vortex specifications, this sprocket delivers the performance and durability demanded by both street and track riders.
