Box One Chromoly Cassette Cog 15T 3/32'' Black

The Box One Chromoly Cassette Cog 15T is built for riders who want a stronger, longer-lasting drivetrain part for single-speed setups. CNC-machined from chromoly steel, it delivers reliable performance and resists wear, while the Shimano-compatible design with a 5mm inner base helps create a secure, stable interface with the cassette body. Finished in electro plated black with laser-etched branding, it’s a clean upgrade that keeps your ride smooth and consistent.
