DURA-ACE Track Cog

The Shimano SS-7600 Dura-Ace is a professional-grade track cog engineered for high-intensity racing and training. CNC-machined from hardened chromoly steel, it offers an exceptional strength-to-weight ratio and superior resistance to wear. This precision manufacturing ensures a perfectly straight chainline, which minimizes friction and prevents unwanted chain tension during peak power output.

Designed specifically for the Dura-Ace 7600 groupset, this cog features standard 1.37" x 24 TPI right-handed threading, making it compatible with most high-end track hubs. The 1/8-inch thickness is optimized for standard track chains, providing a robust interface for fixed-gear use. Trusted by velodrome athletes worldwide, the SS-7600 is the benchmark for reliability and drivetrain efficiency in a 14T configuration.
