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.
