Surly Track Cog: Precision Engineering for Track Cycling Excellence

Elevate your track cycling performance with Surly’s Track Cog—a precision-engineered component designed exclusively for high-speed racing on fixed-gear track bikes. Built from 415 hardened chromoly steel, this cog delivers unmatched durability and power transfer under extreme conditions, ensuring reliability lap after lap on the velodrome or training tracks.

Key Features & Benefits:
– Thread Compatibility: Designed with 1.375″ x 24 TPI right-hand threads (BMX freewheel standard), this cog seamlessly integrates with single-speed rear hubs and BMX freewheel setups—though we recommend pairing it with dedicated track hubs for optimal performance and safety on fixed-gear systems.
– Tooth Count: The 19-tooth configuration provides a high gear ratio ideal for sprinters seeking explosive acceleration and efficiency during races or interval training sessions.
– Material Superiority: Crafted from aerospace-grade chromoly steel, this cog withstands repetitive stress and wear while maintaining lightweight performance—perfect for competitive cyclists prioritizing speed and responsiveness.

Why Choose Surly?
While compatible with BMX freewheel hubs (as noted in our specifications), Surly Track Cogs are purpose-built for track racing applications where precision and reliability are non-negotiable. Unlike generic cogs designed for casual use, this component prioritizes durability without compromising on rotational smoothness—making it an essential upgrade for serious athletes aiming to shave seconds off their lap times.
