Sprockets to Forged Fork Chains
Sprockets to fork chain in the standard version consist of a fixed hub body as well as screwed-on and replaceable tooth segments. The tooth segments are split and in most cases are supplied with hardened tooth flanks. The following sprockets are available from stock:
