Vortex 522ZR-40 CAT5 Rear Sprocket 40 Tooth 520 Pitch

The Vortex 522ZR-40 is a high-performance CAT5 rear sprocket designed for 520 pitch chain applications. This 40-tooth sprocket features Vortex's advanced CAT5 (Computer Aided Technology) design, which uses complex CNC machining to reduce weight while maintaining structural integrity.

Key Features:

• 40 teeth for optimized gearing ratio
• 520 pitch chain compatibility
• CAT5 CNC-machined aluminum construction for reduced weight
• Hard-anodized finish for extended wear resistance
• Self-cleaning mud grooves to prevent debris buildup
• Precision-machined tooth profile for smooth chain engagement

Vortex sprockets are manufactured from high-quality 7075-T6 aluminum alloy and undergo a hard-anodizing process that hardens the surface for maximum durability. The CAT5 design incorporates strategic material removal to minimize rotational mass without compromising strength, making this an excellent choice for both street and track applications.
