Durable Stainless 304 Cog
- Includes 3 M5 pan head cog bolts
Cogs are machined out of 304 stainless steel
- Weight: 15 tooth = 64.3 grams; 18 tooth = 96.3 grams
- Extremely high precision and tolerance on all dimensions. It might fit a little snug at first on some 1/8" chains.
- Our cogs are machined in Woods Hole, Massachusetts, and are now finished by hand in Aromas, California with a bead blast that gives them a distinctive Otis Grey finish
Our cogs are not coated, dipped or anodized. I bead blasts them and we polish each one by hand before sending them to you. You may notice marks leftover from the finishing process. We choose to leave them there because we feel that it is like the grain in a beautiful piece wood. We love how the grain on a piece of wood lends it character and makes it unique. Similarly, we love that each of our cogs is unique and polished by hand, which is why we do not anodize or coat them. Happy riding, Scott and Amalia
