Miche track cogs are made of special heat-treated, nickel-plated steel and use a unique cog carrier that eliminates the repetitious and potentially harmful threading/unthreading that traditional track cogs require.

To install, place the splined cog onto the carrier, grease the threads and use a chainwhip as you would with any other cog, then install your lockring. Once the carrier is securely installed on your hub, you'll only need a lockring tool to swap cogs.

These can be used on any threaded track hub, not just Miche.

We also sell Miche splined cog carriers separately if you need a replacement or spare to keep on another wheel.
