Handmade Mountain Bike Keychain / 28 Tooth Shimano Cassette Cog

Handmade Mountain Bike Keychains: I make these keychains myself using strong rings and chains, and real used mountain bike parts that I chop up and prepare. Check out my other keychains, all assembled in the USA! Note: Many of these mountain bike parts have hard edges, not all are suitable for in-pocket use. Also: These are real used mountain bike parts, they aren't as polished as a brand new part would be. These keychains are segments of a 28 tooth cog, that was liberated from a 9 speed Shimano cassette. Their surface has been fully scuffed up with a small grinding wheel.
