Box One Aluminum Cassette Cog (Black) (3/32″) (13T)

Box One Single-Speed Cogs Description:

Box One Single-Speed Cogs are available now in two different versions — CNC-machined from long-wearing 7075-T6 aluminum alloy or CNC-machined from chrome-molybdenum. Both types are designed to fit Shimano-compatible cassette hubs and have a 5mm wide inner base, giving a more solid interface with the cassette body. The alloy cogs are anodized black with laser-etched graphics, while the chromoly cogs have an ED finish with laser-etched logos.
