Track cog from Soma, for threaded hubs. Both colours are very tough, so if we don't have the size you need in one colour you don't have to feel bad. CNC-machined from hardened chromoly. Not stamped out.
Phosphate black finish. Save some money by not having the shiny finish.
Chrome plating finish in silver, slightly less rust-prone but durability will be the same for either version.
1.37×24 threading
1/8" width (for track chains)
Lockring not included
