Gear change for bicycle hub

摘要

The gear change operating unit for bicycles' multi-speed hubs comprises a housing(1) fastened to the hub axle(2), and a force transmission element(4) installed inside the hub and remote-controlled via a pivoting lever(5). The housing and lever form an axle selector unit which can be dismantled from the hub without the assistance of tools. The pivoting lever and force transmission element in the fitted state of the axle selector unit on the hub axle can be disconnected externally by a manual operation. The lever has a fork end(9) by which the lever is form-lock connected to the force transmission element, and a slide bolt(6) effects disconnection of the pivoting lever from the force transmission element.
