Vortex 827ZR-42 CAT5 Aluminum Rear Sprocket 42-Tooth Red

The Vortex 827ZR-42 is a high-performance aluminum rear sprocket designed for serious riders looking to reduce weight and improve acceleration. This CAT5 series sprocket features red anodized 7075-T6 aircraft-grade aluminum construction that significantly reduces rotational mass compared to stock steel sprockets.

Key Features:

• 42-tooth configuration for optimal gearing options
• CNC-machined from lightweight 7075-T6 aluminum alloy
• Red anodized finish for corrosion resistance and distinctive appearance
• Precision-cut teeth for smooth chain engagement and extended wear life
• Self-cleaning mud grooves to prevent debris buildup
• Considerably reduces unsprung weight for improved handling and response

Vortex sprockets are engineered as a lightweight, high-performance alternative to heavy OEM steel sprockets, allowing riders to fine-tune their bike's gearing for track days, street performance, or optimal fuel economy. The hard-anodized surface provides excellent wear resistance while maintaining a fraction of the weight of steel.
