Surly's sprocket was designed for single speed first and foremost, but it's a bit more versatile for Surly to be Surly.

The base cog is 4.35mm wide and can be stacked several to create a simplified multi-speed drivetrain. In that case, use a 9-speed derailleur.

  • Machining from SCM415 chromoly steel
  • Heat treatment and chrome plating
