Box One 3/32" CNC Alloy 7075 Cog-Black/Silver

The Box One 3/32" CNC Alloy 7075 Cog-Black/Silver is designed to fit Shimano compatible cassette hubs...and ONLY Shimano compatible cassette hubs. So no trying to sneak it onto a Campagnolo cassette hub! It works with 3/32" and 1/8" chains, is lightweight, and has a wider inner base for firm, rock-solid contact with the cassette. The yin-yang reminiscent look is a result of the whole cog being anodized black then laser etched to create the graphics. Neat trick!
