Vortex 201ZB-42 530 Steel Rear Sprocket 42-Tooth Black

The Vortex 201ZB-42 is a 530-pitch, 42-tooth steel rear sprocket finished in an electro-plated satin black coating for corrosion resistance. Engineered to Vortex's exacting tolerances, this sprocket is CNC-machined from carbon steel alloy and features Vortex's patented tooth profile, which is designed to extend sprocket life and improve chain engagement compared to standard OEM designs.

Lightening holes are machined into the carrier to reduce rotating mass without compromising structural integrity, delivering a responsive feel on the road or track. The black finish provides a clean, aggressive look while protecting against the elements.
