Vortex 210ZK-36 CAT5 Aluminum Rear Sprocket 36T 520 Black

The Vortex 210ZK-36 is a CAT5 lightweight aluminum rear sprocket featuring a 36-tooth count and 520 pitch, finished in a striking black anodized coating. Engineered for performance-oriented riders, this sprocket is 100% CNC manufactured in the USA from a specially formulated aluminum alloy developed to Vortex's exacting standards.

The CAT5 design uses a unique color anodizing process that excludes the sweeps, mud grooves, and teeth — delivering a vivid black finish with bright silver highlights on the functional contact surfaces. The result is a sprocket that performs at a high level while maintaining a race-inspired appearance.

Key Features:

• Lightweight CAT5 aluminum construction reduces rotating mass for improved throttle response and acceleration
• 36 teeth / 520 pitch for precise gearing application
• Black anodized finish with silver highlights on teeth and grooves
• 100% CNC manufactured in the USA to tight tolerances
• Specially formulated alloy per Vortex specifications for strength and durability
• Patented Vortex tooth design increases sprocket longevity and reduces chain wear
• Sold individually (single sprocket)

The Vortex 210ZK-36 is the preferred choice for street and track riders seeking a direct performance upgrade over heavy OEM steel sprockets without sacrificing durability or fit quality.
