Surly Single Speed Cog: Versatile & Durable Drivetrain Solution

Engineered for riders who value simplicity and reliability, this precision-machined cog excels as a dedicated singlespeed component while offering clever multi-gear flexibility. Crafted from hardened SCM 415 chromoly steel, it withstands brutal urban commutes, gravel adventures, and daily belt-drive punishment without compromising tooth integrity.

Key Advantages:
– Dual-Purpose Design: Primarily optimized for crisp singlespeed performance (3/32″), yet compatible with 9-speed shifters when stacked—ideal for temporary gear experiments or budget-conscious conversions
– Unmatched Durability: Chromoly steel construction resists wear from chain tension and all-weather riding, outperforming standard alloy cogs
– Precision Fit: Seamlessly mounts on Shimano HG freehub bodies (7/8/9/10-speed compatible) for hassle-free installation
– Low-Maintenance Focus: Perfect for fixed-gear enthusiasts, belt-drive setups, or riders minimizing drivetrain complexity

Ideal For: Urban commuters tackling potholes, bikepackers needing reliability off-grid, or mechanics building bomb-proof winter bikes.
