Shimano Dura-Ace 1/8" Track Cog, Black

The Shimano Dura-Ace 7600 Track Cog is CNC machined to ensure a precise chain line, so you don’t have to deal with unwanted chain tension. The Chromoly construction is designed tough so that you won’t have to worry about wearing down your sprocket and/or chain when you’re training hard.

The cogs have a right-handed threading of 1.37" x 24 TPI. These cogs live up to the Dura-Ace name, which you expect from all top-end Shimano parts. Comes with four options for teeth count ranging between 13T and 16T in either 1/2" X 1/8".
