Know before you buy
Yes, this cog is designed to fit onto standard Shimano-style splined cassette freehub bodies. It is intended for single-speed conversions, so you will need to use spacers to achieve the correct chainline.
Chromoly steel is significantly harder and more wear-resistant than standard aluminum or mild steel. This ensures the teeth maintain their shape longer under high torque, providing consistent power transfer and preventing premature chain skip.
This cog is optimized for standard 1/8-inch single-speed chains. While it may accommodate some 3/32-inch chains, a 1/8-inch setup will provide the most secure and durable interface.
This cog is designed for cassette-style freehub bodies, which allow for coasting. It is not compatible with fixed-gear hubs that require a threaded cog and lockring.
No, the cog is sold as a standalone component. You will need to purchase a separate single-speed spacer kit to properly position the cog on your freehub body and achieve the correct chainline.
