How much do you know about the wiring types of brake cables and variable speed cables?

External routing

External wiring, as the name implies, is that the brake cable extends from the outside of the frame to the transmission kit and brake components. This wiring method is considered an older wiring method. Basically, many new cars do not use this method for wiring. . The advantage of this wiring method is that it is more convenient and quick to maintain and repair the brake cable and the transmission line tube. But the shortcomings are also obvious. The appearance of the bicycle is not strong, and it is troublesome to wipe and wash the car. You need to be careful not to let it get wet, otherwise it is easy to be polluted and affect the brake and shifting, because it is on the outside of the frame. So it is easy to be contaminated and damaged, leading to braking and shifting performance.

Internal routing

Internal wiring means that the brake cable and the transmission line tube are routed from the inside of the frame when they go from the front of the car to the brake or the transmission kit. Now many road and mountain bikes are routed through this type of wiring method. And the advantages of this wiring method are obvious: the overall sense of the car is stronger and more beautiful; when washing the car, you don’t have to worry about the brake and transmission line pipes like external wiring; at the same time, because the wiring is inside, it is aging. The degree will be greatly reduced. But the shortcomings are fatal: it is troublesome to repair or replace brake cables or transmission cables.

To sum up, how to lay the line is actually related to the cost of the vehicle. Because the inner wiring has higher technical requirements, the inner wiring car is generally more expensive for the same-level outer wiring car, although there are some Exception, but also a small part. Some riders like to walk outside, and some like to walk inside, so if you want to understand your own preferences, you have to experience and explore by yourself. I can only let everyone know, but I can’t define which one is good and which one is bad. Choose or see what you like.
