Do you know the seven major technological innovations that change the development of road bicycles?


Bicycles have been invented and used for two hundred years. In the past two hundred years, human beings have been trying to make many modifications and improvements on the research and development of bicycles, so that they have changed in the sky over the years, making them completely A “modern machine”. Today, I will take you to understand what are the major stages of the historical development of road bicycles.

1. Safety bicycle


As early as the late 1800s, if you want to have a bicycle, it is impossible. It will be a symbol of the aristocratic identity. At that time, the bicycle passed the pedal directly on the huge front wheels through the front wheels, and passed the inertia driver. According to reports, such bicycles, normal riders can maintain a maximum of 40km/h, which is very dangerous. Fundamentally, the bicycle was not safe before this kind of bicycle.

In order to solve this problem, safety bicycles were introduced. Use two closer wheels means that the rider’s feet can reach the ground, which makes it easier for parking and getting on and off. British engineer Henry J. Lawson’s original model was improved, and he used the pedal to pass the power from the pedal to the wheel. It was quickly replaced by the chain. The method of the chain transmission is still in use.

2. Flame tire

The first tire on the bicycle we know is to use solid rubber bands, with the edge of small rims. In 1887, John Boyd Dunlop produced a world’s glutinous tires for his son’s bicycle to help him relieve headaches when riding. Later, Dunlop tires were established, and methods to prevent tires were found, such as adding a hard canvas layer to rubber. But these are not demolished.

Until 1891, édouardmichelin developed a tire that could be fixed on the wheel with a clip, and then disassembled to repair the tire. The adhesive on the adhesive tube followed, and later developed into a combination of elbow and inner tires. Now, you can find this combination on 99 % of bicycles.

3. Fast disassembly system


The fast -discharge system is another invention proposed by Tullio Campagnolo. As we mentioned earlier, before the rear -dial -chain system is widely popularized, to change the gear, we must first remove the rear wheels and then replace it.

At that time, Campagnolo’s driver was unable to disassemble the screw of the fixed rear wheels during the cold weather. It was difficult to remove the wheels, so as to waste precious time in the game. This sense of frustration is the origin of invention of fast -demolition rods in 1927.

The emergence of the fast -disassembly system means that the process of disassembling and replacement of the wheel has been greatly simplified. Fast disassembly is crucial for Campagnolo’s Cambio Corsa chain system. It plays a certain role in mobile.

4, helmet

In the 1970s, the helmet appeared for the first time. At that time, the riders used more of the helmets made of leather. Although this helmet can provide some protection for the driver during cycling, this protection is only for the crickets for 剐 剐 剐In terms of, the impact force caused by the car does not have much protection.

With the prevalence of the bicycle motion, the American MSR and Bell companies are first involved in the design of modern bicycle helmets. They are developed based on motorcycle helmets and racing helmets. Polycarbonate plastic as a shell.


In 1975, Bell BIKER first developed a bicycle helmet that meets the CPSC standard. This is the first bicycle helmet to use ABS plastic as a shell. The benchmark of the industry. Later, the updated shell material PVC and high -priced material polycarbonate were used, which greatly reduced the weight of the helmet. In the past ten years, most bicycle helmets have similar styles to BIKER.

In the early 1990s, Bell split the helmet business. With the development of the helmet shell manufacturing technology, the appearance of the helmet has changed hugely. And this design is still used on many helmets.

5. Locking foot


Although the first -footed pedal in history was technically manufactured by Charles Hanson in 1895, in the 1970s, the M71 -locking foot of M71 made by Italian company CINO CINELLI. But the foot can only drive the switch manually to unlock the lock. Until 1984, LOOK decided to use the bundle system similar to the downhill skiing to design the first automatic foot -locking pedal.

LOOK PP65 Highway Locking can be unlocked by turning the shoe outward, and at the same time, you only need to step on the lock film into the pedal. In 1985, Bernard Hinault rode the look This lock has won the championship of the Tanfa bicycle race. Since then, LOOK has become famous in the field of road pedals. Although there are companies such as Time or Speedplay, other designs are provided, but in the cycling pedal today, the cyclist presses down to combine the anti -slip nail, and then rotate the heel outward to release its principle.

6. Carbon fiber frame

As an emerging material, the emergence of carbon fiber composite materials has also changed the development of road bicycles. Carbon fiber not only has the inherent characteristics of carbon materials, but also the soft processability of textile fibers. It is less than 1/4 of the steel, but its strength is very strong.


In 1999, Lance Armstrong rode on Trek’s OCLV carbon fiber bicycle to win the Tourism bicycle race. This is the first carbon fiber bicycle to win the tour. This proves that the characteristics of carbon fiber can help players get better results and create new records.

Carbon fiber has the characteristics of light weight and high strength, and can achieve special shape structure without sacrificing basic characteristics, which means that most of the high -end top bicycles will be made of carbon fiber. Most of the components may be made of carbon fiber. Carbon fiber bicycles surpass metal bicycles at least at least at the professional level.


Today, although steel and alloys still occupy an absolute position, the use of carbon fiber in high -end bicycles is very common.

7. Electronic change

In the 1990s, Charles IdouX led the Mavic team early, developed an electronic transmission system, and named ZAP. However, attempts to use Suntour’s BEAST and MAVIC ZAP electronics transmission, due to various problems, they have not succeeded in use due to various problems. ZAP’s fate is extremely bumpy …

Nevertheless, Chris Boardman, a driver, used Mavic’s electronic transmission to win the 1994 Circle Bicycle Race. In addition, Zap Mavic System has also won the “Innovation Award” in the United States.

Until the emergence of the emergence of the DI2 electronic transmission system of Jewisho changed all, its fine control, the powerful, accurate, and clear gear replacement speed reached a certain level. Although some people have some questions about electronic changes, the birth of Shimano DI2 will definitely be a major innovation in the development of road bicycles.

Subsequent manufacturers Campagnolo launched EPS and SRAM to launch ETAP electronic changes. Although the prices were very expensive at the beginning, they did not change the industry’s confidence in electronic changes. Today, it is rare to see a group of mechanical transmission kits in the top competitions of this sport, and it is becoming more and more difficult to buy a contemporary flagship bicycle with mechanical transmission.


The world is changing,

Bicycles are also changing,

There are endlessness
