Vortex 720FZB-49 Rear Sprocket 49 Tooth 520 Pitch

The Vortex 720FZB-49 is a high-performance rear sprocket designed for serious riders seeking the optimal balance of strength and weight savings. This 49-tooth sprocket features Vortex's proven CAT5 construction, combining a lightweight 7075-T6 aluminum carrier with a hardened steel tooth insert for maximum durability where it matters most.

Key Features:

• 49 teeth for optimized gearing and acceleration
• 520 pitch chain compatibility
• CAT5 hybrid construction: aluminum body with steel tooth insert
• Precision CNC-machined from aerospace-grade 7075-T6 aluminum
• Heat-treated steel teeth for extended wear life
• Self-cleaning mud groove design prevents debris buildup
• Anodized finish for corrosion resistance
• Weighs significantly less than all-steel sprockets

Vortex sprockets are manufactured to exacting tolerances and undergo rigorous quality control testing. The hybrid design delivers the durability of steel teeth where chain contact occurs, while the aluminum carrier reduces unsprung and rotating weight for improved handling and acceleration response.
