Surly Single Speed Cog – Durable & Versatile Freehub Sprocket

Built for simplicity-focused cyclists, this precision-engineered single speed cog delivers reliable performance whether you’re commuting, fixed-gear riding, or customizing a minimalist drivetrain.

Key Features:
– Dual-Purpose Design: Primarily for single-speed setups but compatible with 9-speed shifters when stacked (note: multi-gear shifting may be less responsive than dedicated cassettes)
– Premium Chromoly Steel: SCM 415 hardened construction resists wear and extends lifespan under heavy pedaling loads
– Shimano Freehub Ready: Seamlessly fits standard Shimano 7-speed splined cassette bodies
– 15-Tooth Precision: Optimized for 3/32″ chains, balancing speed and torque for urban or trail use

✔️ Low-Maintenance Reliability – Ideal for singlespeed conversions or riders prioritizing durability over complex gearing
✔️ Backup Compatibility – Unplanned multi-gear setup? This cog adapts in a pinch
✔️ Proven Material – Chromoly steel outperforms basic alloy cogs in stress resistance
