Transmission cables and brake cables are one of the inconspicuous roles in bicycle accessories. However, cyclists have such experience that the line brake or line change feel of old and new cars is very different. It is either tight or astringent or slow. In short, it is difficult to be in the right state. This is because a smooth, durable and safe pipeline is not that simple.
The structure, principle, and manufacturing of the bicycle transmission line and the brake line are interoperable, so the following will introduce them together to help riders understand more ways of the bicycle pipeline, and they can also choose a more suitable one when purchasing.
The inner wires (cores) of the brake cable and the shifting cable are made of twisted steel wires, and there is no essential difference except the thickness. The inner cable of a brake cable is made up of 19 hair-thin steel wires with a diameter of about 1.5-1.6 mm, and the transmission cable can be slightly thinner about 1.1-1.2 mm.
The difference between the brake cable and the transmission cable and their respective grades lie in the grinding, coating, and covering of the steel wire, the design of the outer tube material, and the difference between whether or not it is filled with oil. Each grade of steel wire has a corresponding grade of outer tube to achieve complementary effects.
The inner cable material is divided into two kinds of galvanized steel wire and stainless steel wire. The grade of the inner cable mainly lies in the processing technology.
The most basic inner cable is without any treatment; the second grade needs to be finely ground to make the surface smoother; the third grade inner cable is The surface coating is processed, and the professional inner line, which is more durable and smoother through more advanced coating and rigorous technology, is the fourth level.
The first grade is used on commuter bikes, the second and third are used for competition training bicycles, and the fourth grade is mostly used by professional riders. In order to further improve the smoothness. It is recommended that the inner line above the second level be matched with the oil injection line pipe to achieve a better effect of complementarity.
Grinding core and coated core, which is more durable depends on usage habits.
In the development direction of professional-grade inner line, the traditional coating lubricating material and grinding lubricating process can no longer meet the long-term and durable needs.
In order to meet the professional requirements for more durability and smoothness, each company is developing the fourth-level inner line, such as the 9000 polymer coating used by Huafeng, which makes the inner line of the brake cable smoother and the price is very moderate.
In the future development of internal smooth technology, grinding has greater cost and process space. With the development of grinding technology and the increase in scale, more and more riders can enjoy the ultimate experience brought by nanotechnology.
