Shimano / 喜马诺

Shimano is the Japanese bicycle-component company at the center of No.199 自行车 200年’s supply-chain argument. The source traces Shimano from a 1921 Sakai metalworking shop into a drivetrain and components company whose cold forging, tooth-profile design, derailleur structures, cables, chains, tolerances, and patents made it difficult for assemblers to replace.

Shimano’s importance is system-level rather than single-part. The episode says the SIS indexed-shifting system turned shifters, cables, derailleurs, cassettes, and chains into a matched stack, making Bicycle Component Stack Power a profit and control point while many finished-bicycle factories stayed lower-margin.
