Rear Sprocket - Aluminum - 51 Tooth - Black
The RENThAL Rear Sprocket is a CNC-machined aluminum sprocket designed with a computer-aided ultra-light construction. Its lightweight design helps reduce unsprung weight and increase power transfer. Finished in black, this 51-tooth rear sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum.
The aluminum construction is 33% lighter than steel while maintaining strength. A special tooth profile allows the chain to roll easily on and off the sprocket, helping promote longer wear, reduced noise, and increased power transfer. The manufacturer part number is 224U-520-51GPBK.
