Vortex 347ZB-48 Aluminum Rear Sprocket 48-Tooth Blue

The Vortex 347ZB-48 is a high-performance aluminum rear sprocket featuring 48 teeth and an attractive blue anodized finish. Designed as a lightweight alternative to heavy steel sprockets, this precision-engineered component reduces rotating mass to improve acceleration and overall bike performance.

Key Features:

• 100% CNC machined in the USA to the tightest tolerances for perfect concentricity
• Lightweight aluminum construction significantly reduces rotating weight compared to stock steel sprockets
• Blue anodized finish provides corrosion resistance and distinctive appearance
• Vortex patented tooth design reduces friction and drag for improved acceleration and deceleration
• Precision manufacturing ensures extended chain and sprocket life
• Lightening holes strategically placed to minimize weight while maintaining strength
• Hardened teeth for increased longevity and wear resistance

Vortex aluminum sprockets are engineered for riders seeking maximum performance gains through weight reduction. The precision CNC manufacturing process creates a perfectly concentric sprocket that frees up horsepower and reduces drivetrain friction, while the blue anodized coating helps prevent corrosion and delivers a custom appearance.
