Box Pinion bmx cog
The new Pinion Cogs are offered in two ranges; CNC-machined from long-wearing 7075-T6 aluminum alloy and CNC-machined chromoly. 3/32” cogs are available in 13-18-tooth sizes. Both types are designed to fit Shimano-compatible cassette hubs. Both have a 5mm wide inner base, giving more solid interface with cassette body.
Alloy cogs are anodized black with laser-etched graphics, while chromoly cogs are electro plated black with laser-etched logos.
