Description

Unsprung weight directly impacts your bike's throttle response, acceleration, and handling precision—and this Renthal rear sprocket eliminates unnecessary mass where it matters most. By swapping to a CNC-machined 7075-T6 aluminum design, you'll gain 33% weight savings over steel while maintaining the durability required for high-rpm track sessions. The engineered tooth profile keeps your chain meshing cleanly, reducing drag and noise while extending component life across the drivetrain.

  • 43-tooth configuration
  • 7075-T6 aluminum
  • 33% weight reduction vs. steel
