GFRA "GoFast" 520 Conversion Street kit with hardcoat aluminum rear sprocket. Gearing one down in front, stock rear. SX3 Vortex Chain.

Vortex Steel Front Sprocket

  • Drilled lightening holes reduce rotating mass
  • High carbon steel for maximum strength
  • Special Vortex Nichel plating to resist corrosion
  • Induction hardened to reduce surface wear
  • Precise tolerances to ensure concentricity

Vortex F5 Rear Sprocket

The F5 PTFE Black Hardcoat is built for endurance. After hard anodizing with a jet black dye, Vortex then coats the sprocket with PTFE for added lubricity. The result is an ultra tough, ultra light sprocket that stays cleaner and lasts longer. A Vortex sprocket is a lightweight high-performance alternative to the steel stock sprocket. Use Vortex sprockets to considerably reduce mass and to change your gearing. Made with highest quality aluminum.

  • 7075 T6 aluminum is the best grade material for light weight and durability.
  • The weight you save on drive components is multiplied as rotating mass.
  • Less rotating weight improves acceleration.

Vortex SX3 Chain

  • Drilled links reduce rotating mass
  • X-ring seals to reduce friction
  • Improved tensile strength
