Renthal Ultralight Aluminum Rear Sprocket Black 52 Tooth (112U-520-52GEBK)
- Renthal sprockets are CNC-machined (not stamped) and feature a computer-aided "Ultra light" design to reduce unsprung weight and increase power transfer
- Rear sprockets are made from high-strength, specially enhanced 7075 T-6 aluminum - 33% lighter than steel - to further reduce weight and increase power transfer without sacrificing strength
- Rear sprockets also feature special tooth profile that allows the chain to roll easily on and off the sprocket for longer wear, less noise and more power
- All Renthal rear sprockets are hard anodized
