Description

Technical Field

[0002] Road bikes are already very common in our daily lives. For most people, the difference between road bikes and ordinary bikes is whether they can change speeds. With the development of technology, the speed change of road bikes can be achieved through the speed change system.

When in use, the spacing between the adjustment base columns is reduced to adapt to the length of the speed-changing drum element. The clamping block bodies are close to each other to prevent the speed-changing drum element from shifting. Compared with the traditional method, while ensuring firm clamping, the angle of the speed-changing drum element can be adjusted more conveniently to reduce the hole position deviation.
