Description

The Renthal 150U-520-52GBBK is a rear sprocket designed for off-road use. It is CNC-machined from high-strength 7075-T6 aluminum, making it 33% lighter than steel. This ultralight design reduces unsprung weight and increases power transfer.

The sprocket features a special tooth profile that allows the chain to roll on and off smoothly, contributing to longer wear, reduced noise, and improved power output. It is finished in black and designed for 520 chain size with 52 teeth.
