Besides the stock bore we also can supply these sprockets with a specific plain or finished (has key-way and set screws) bore size. We also offer upgrades on our double D12B21 sprockets such as black-oxide coatings and heat-treated hardened teeth, though we often have these specific sprockets with those features already added right off the shelf.
