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.

Really nice little part. Feels great on the chain, super light I swear the packaging weighs more than the cog. The fit it real snug without being overly tight. I’d buy again in a heartbeat.
