- 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.
Made with the 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 RX3 Chain
- Drilled links reduce rotating mass
- X-ring seals to reduce friction
- Improved tensile strength
