Cog architecture has been engineered to work with both inner and outer links of the chain, which allows extremely refined shifting for both inboard and outboard shifts.
The Box Three cassette draws from both of its Box One and Box Two siblings to create a sensible all-rounder. All cogs are stamped from steel and subsequently, the larger ones are pinned to steel spiders.
