Vortex 120A-54 Aluminum Rear Sprocket - 54 Tooth

The Vortex 120A-54 is a high-performance aluminum rear sprocket designed for serious riders who demand both weight savings and durability. This 54-tooth sprocket is precision-machined from lightweight 7075-T6 aircraft-grade aluminum alloy, providing exceptional strength while significantly reducing rotational mass compared to steel sprockets.

Key Features:

• 54 teeth for optimized gearing and acceleration
• 7075-T6 aircraft-grade aluminum construction for superior strength-to-weight ratio
• CNC-machined with tight tolerances for precise fitment and smooth operation
• Hard-anodized finish for enhanced wear resistance and corrosion protection
• Self-cleaning mud grooves help prevent debris buildup
• Lightening holes reduce weight without compromising structural integrity

Vortex sprockets are manufactured to exacting OEM specifications and feature advanced design elements including radius cut tooth profiles that improve chain life and performance. The hard anodizing process creates a durable surface that resists wear while maintaining the lightweight benefits of aluminum construction.
