Vortex Steel Rear Sprocket 438S-47

Description

Vortex Steel Rear Sprocket
Steel front sprockets are precision-manufactured and induction-hardened to precise tolerances to improve concentricity and provide a stonger, quieter and longer-lasting sprocket
Plated to resist corrosion
Rear sprockets are available in aluminum, F5 PTFE, CAT5 and steel
F5 PTFE black is built for endurance and is hard anodized with jet-black dye, then coated with PTFE for added lubricity
CAT5 are CNC manufactured to the tightest tolerances with a unique tooth design: color anodizing which excludes the sweeps, mud grooves and teeth for a flash of color
Steel rear sprockets are made from carbon steel and electroplated with a satin black finish that resists corrosion; teeth are hardened so sprocket will hold up to many miles, without affecting strength
Steel rear sprockets are also cupped down from the tooth ring to body to reduce as much weight as possible
