Box Pinion Single Speed Cassette Cog
New Pinion Single-Speed Cogs are now offered in two different materials: CNC-machined from long-wearing 7075-T6 Aluminium alloy or CNC-machined chromoly. The 3/32" cogs are available in 14 tooth alloy and 15 or 18 tooth Chromoly sizes. 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. Alloy cogs are anodized black with laser-etched graphics, while chromoly cogs are electro plated black with laser-etched logos.
