The Gusset FCGU317 CNC steel track cog is built for riders who want reliable power transfer and long service life. CNC-machined from hardened steel, it maintains accurate tooth profiling and consistent chain engagement under load.

This cog uses a standard threaded interface (1.37″ × 24T), making it compatible with most track and fixed-gear hubs. The 17T size suits faster ratios for track riding, training, and urban fixed-gear builds, while the 3/32″ width works with common singlespeed and track chains.

Manufactured by Gusset, it’s designed to handle high torque and daily riding with confidence.

This item is New Old Stock and in original packaging. It’s unused, factory packed, and ready to install.
