The Chris King Single speed Cog is designed to convert cassette drive bodies into single speed. If you’re going to run just one gear it may as well be the very best you can get. Chris King's stainless steel cogs are bead-blasted following heat-treating with sizes ranging from a leg-searing 12t through a sit-and-spin 20t.
- Manufactured at Chris King's Portland, OR facility
- Required splined spacers for proper installation
