Product Details

The Vortex 144BZK-39 is a high-performance CAT5 aluminum rear sprocket featuring 39 teeth. Engineered for serious riders who demand both performance and durability, this sprocket combines lightweight construction with race-proven strength.

Key Features:

  • CAT5 hard-anodized aluminum construction for superior wear resistance
  • 39-tooth configuration for optimized gear ratios
  • CNC-machined from high-grade 7075-T6 aluminum alloy
  • Hard-anodized finish provides extended service life
  • Precision tooth profile ensures smooth power delivery
  • Significantly lighter than steel sprockets while maintaining strength
  • Self-cleaning mud groove design prevents debris buildup

Vortex CAT5 sprockets are designed to meet the demands of both street and track use, offering an excellent balance of weight savings and longevity. The advanced anodizing process creates a hardened surface that resists wear while the lightweight aluminum construction reduces unsprung weight for improved handling and acceleration.
