• Reduced rotating mass — lightweight aluminum design lowers unsprung weight, improving acceleration, deceleration, and directional changes
• Vortex patented tooth design — unique profile increases sprocket longevity and chain engagement
• 100% CNC manufactured in the USA — produced to the tightest tolerances in the industry
• Gunk-clearing grooves between teeth help shed debris and extend service life
