Description

The Box One Pinion cog is CNC machined from chromoly and made to fit Shimano compatible cassette hubs. It comes in 3/32 inch sizes from 13 up to 18 tooth, so you can set your gearing where you want it.

A 5mm wide inner base gives a more solid interface with the cassette body. The chromoly cogs are electro plated black with laser etched logos, while the same cog is also offered CNC machined from 7075-T6 aluminium.
