47T Sprocket

Description

• CNC-machined (not stamped) and feature a computer-aided ultra-light design to reduce unsprung weight and increase power transfer
• Rear sprockets made from high-strength, specially enhanced 7075-T6 aluminum that is 33% lighter than steel to further reduce weight and increase power transfer without sacrificing strength
• Rear sprockets also feature a special tooth profile that allows the chain to roll easily on and off the sprocket for longer wear, less noise and more power
• Front sprockets made from case-hardened, core-refined nickel-chrome-molybdenum alloy steel for the ultimate combination of strength and hardness
