New Pinion Single-Speed Cogs are now offered in two different materials: CNC-machined from long-wearing 7075-T6 aluminum alloy or CNC-machined chromoly. 3/32” cogs are available in 13 to 18-tooth 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.
