Internal cable

Internal cable routing refers to the tubular component inside the bicycle frame that is used to guide cables (such as brake cables and shift cables), allowing the cables to be hidden inside the frame, which is both beautiful and protects the cables, reducing wind resistance and the impact of the external environment.

Specifically, the functions of the built-in cable tube include:
Aesthetics: The cable tube is no longer exposed, making the overall appearance of the bicycle more concise and smooth.
Protection: The cable tube is protected by the cable tube and is not easily damaged by external factors such as mud and water splashes, extending the service life.
Reducing wind resistance: The hidden cable tube can reduce wind resistance and increase riding speed.
Prevent entanglement: During riding, the cable tube can effectively prevent the cable tube from entanglement with other components to avoid accidents.

In summary, internal cable routing is a commonly used technology in modern bicycle design, and plays an important role in improving the performance and appearance of bicycles.
