Surly Single Cassette Cog

Features

• At the base, each cog is 4.35 mm wide, which allows you to stack a few of them up for a simplified multispeed drivetrain—use a 9-speed derailleur if you do that
• Multigear use will result in slower, less-crisp shifting than cogs designed for multigear systems
• Machined from SCM415 chromoly steel; heat-treated and chrome-plated for strength and durability
• Cogs work with 6- to 9-speed, 3/32 in. chains
• Compatible freehub: Shimano Hyperglide (HG)
