Vortex 193AZB-50 520 Aluminum Rear Sprocket 50-Tooth Black

The Vortex 193AZB-50 is a 50-tooth, 520-pitch black anodized aluminum rear sprocket built for performance-oriented street and track riders. Manufactured using a specially formulated aluminum alloy and precision CNC-machined in the USA, this sprocket delivers an optimal blend of lightweight performance and durability.

Key Features:

• 50-Tooth / 520 Pitch: Designed for use with 520-pitch drive chains; 50-tooth count increases rear wheel torque for stronger acceleration
• Lightweight Aluminum Construction: Reduces rotating mass compared to steel sprockets, improving throttle response and overall handling
• Black Anodized Finish: Hard-coat black anodizing provides corrosion resistance and a clean, aggressive look
• 100% CNC Manufactured in the USA: Precision machining ensures true concentricity for smooth, quiet operation
• Specially Formulated Alloy: Material engineered to Vortex specifications for superior strength-to-weight ratio
• Vortex Patented Tooth Design: Unique tooth geometry extends sprocket longevity and improves chain engagement efficiency
• Weight-Reducing Cutouts: Strategically placed lightening holes minimize rotating mass without sacrificing structural integrity

The Vortex 193AZB-50 rear sprocket is an excellent choice for riders looking to optimize their gear ratio for increased low-end pull and acceleration. As a direct bolt-on replacement, it pairs seamlessly with Vortex front sprockets and 520-pitch chains.
