four. Number of teeth
5. Hub diameter (DH) and length (L) (from the situation of non-standard sprockets)
six. Whether the tooth heads are hardened
Specify the next goods, in case the chain No. is unknown
1. Tooth thickness (T)
2. Root diameter (DB) (Caliper diameter (DC) from the situation of odd-number teeth)
