The rear gearbox hook used for installation on the bicycle fork not only fixes the gearbox, but more importantly, it can absorb the impact force and break in the event of severe impact (such as a fall), thereby protecting the frame and gearbox body from damage. Made of aluminum alloy through CNC machining, it has high strength and lightweight, ensuring fracture protection during impact and preventing damage to the transmission body and frame. Surface anodizing treatment has good corrosion resistance and can cope with various riding environments, including wet, muddy, or gravel roads. Easy and fast replacement, only a hex wrench is needed to complete disassembly and assembly, suitable for self replacement or quick maintenance during cycling events, saving time and effort.
