COG1218L is a cog and lock ring wrench designed from a mechanic's request for a tool that can remove cogs ranging from 12 to 18 teeth. Mechanics and cyclists who change cogs many times a day will surely feel the time savings.

One side is for 12-15t cogs, and the other side is for 16t-18t cogs. The protrusion of silver plate on the 12-15t side is for lock rings.

This wrench is quite effective on sprockets that are firmly fixed to the hub because it can transfer torque directly to the hub. Please note that it cannot be used with aluminium or carbon sprockets.

We aimed for a design that can be used for a lifetime. The lock ring plates are replaceable if damaged. You can purchase replacement lock ring plates here.
