Vortex 435CK-42 F5 Aluminum Rear Sprocket 42T 525 Pitch Black Hardcoat

The Vortex 435CK-42 is a high-performance F5 aluminum rear sprocket designed for riders seeking reduced rotating mass and enhanced acceleration. Manufactured from 7075 T6 aluminum, this sprocket offers the best grade material for light weight and durability, with CNC machining to the tightest tolerances creating a perfectly concentric sprocket every time.

Key Features:

• Hard anodized with a jet black dye, then coated with F5 PTFE for added lubricity
• 100% CNC manufactured in the USA
• Perfected tooth design has less drag and reduces friction for better acceleration and deceleration
• 42 teeth, 525 pitch chain compatibility
• Considerably reduces mass compared to steel stock sprockets
• Mud grooves and coatings help keep components clean

The ultra-tough PTFE coating creates an ultra light sprocket that stays cleaner and lasts longer. The weight saved on drive components is multiplied as rotating mass, and less rotating weight improves acceleration. This sprocket features Vortex's patented design for precise power transfer and extended component life.
