Tonight, Zhang Yuan studied for more than 4 hours in the "car sinus" of Huang Qiang and his wife, until after 9:30 in the evening, Zhang's mother (called He Guiying, generally called her "good aunt") went to the door of the strongest store and urged Zhang Yuan to go home for dinner.

Zhang Yuan also kept in mind that the various bicycle questions and the use of various parts raised by Huang Qiang today, Zhang Yuan was full of expectations for tomorrow's exam, and at the same time, he was also a little worried about what problems Huang Qiang would ask...

The next day, Huang Qiang only asked a set of questions (not a topic but a question related to a part, called a group): How does the chain measure the wear and tear of a bicycle? How do you maintain your chain to last the most during the race?

Zhang Yuan replied: The life of the bicycle chain depends on the chain-checker, which measures the current degree of chain wear. Proper maintenance of the chain can make the drivetrain more efficient and even extend the life of the chain up to 10,000 km. However, it should be noted that wear tests have shown that every hundredth of the elongation loss of the chain reduces the power by 2W. Therefore, the bicycle chain can be replaced after 3 to 4,000 kilometers to ensure efficiency and safety.

Huang Qiang didn't expect this dimple young man to have such a good memory, even Chain checker can speak, and his English is a bit level, very good. After asking, continue to study today... Learn what pedals are and what wind resistance and direction they are. If so, from Wednesday to Friday, they studied tires, brake suspension, bracket seat assembly and other things in the "car sinus", until Friday night, after completing the study, Mrs. Huang asked Zhang Yuan to arrive on time at 1 pm on Saturday, and he had to wear sportswear and sneakers.

At 12:45 p.m. on Saturday, Little Angkor was chatting with a few teenagers outside the car shop, not counting Little Angkor, there were 6 people here, 4 of them were older, about 15-16 years old;

The other two are about the same age as Zhang Yuan, both are boys around 13-14 years old, and they are both wearing light and comfortable sportswear. It seems that they are very familiar with each other. Everyone talked and laughed happily, and the state was relaxed.

Zhang Yuan rode the big buffalo to the strongest bicycle shop, got off the bike, and greeted Little Angkor first, and at the same time nodded hello to the rest of the people. Xiao Wu pointed at Zhang Yuan and said to the others: He is Xiao Zhang of the T15 group newly recruited by the boss, Zhang Yuan. Ah Yuan, I would like to introduce you to your team members, who wear red pants called Awen, and English is called Man, and those who wear white pants are Geji, Geroge, the T15 group of our "strongest bicycle shop" "Jinchong" team, our bicycle shop has a total of 4 bicycle racing teams, respectively

Adult menstruation, over 21 years old, can be called semi-professional team, Group F

The T21 group, under the age of 21, is also a semi-professional team, the same as the adult group F, but the age difference

T18 group, under 18 years old

T15 group, under 15 years old

Our team is called "Rush Cycling", remember! Otherwise, if someone asks you what kind of cycling team you are, and you say you don't know, then we won't have the face.

In addition, the 4 seniors who are taller are the T18 team, the first is called Ah Xing (wearing a red vest), the second is Da Jiu (naked), the third is Zhu Zai (also a red vest, a pair of OK brand sports sunglasses), and the last one is the same red vest, with a yellow star on his left chest, and a YIKE sports cap on his head, Wu Xiaoge calls him Nobita.

After introducing them, Wu Xiaoge pointed to the three stronger and older riders in the bicycle shop, and said: Our T21, which can also be said to be a semi-professional team, also known as the F Group League, this person wearing a silver vest and wearing AXIS sneakers is called Ming Zai, wearing MIZONO shoes is called Silly Leopard, wearing red and white shoes KSWEET is called Andy, and I, Wu Tianzhen is the squad leader of your three groups, so I work in the shop and help the master (Huang Qiang) take care of the daily operation of the car shop.

Ah Yuan, there is also a T15 student who has not arrived, his name is Ah SAM, Huang Mingshan, is the son of Boss Huang, and he will come back soon.

As soon as Cao Cao was said, Cao Cao arrived, a boy who was very similar to Mrs. Huang, but was tall and thin but strong, about 172 cm tall, arrived in a chariot, before anyone arrived, the voice had already come, saying: Hi! Companions, I am not late, 12:00 punctuality, there are still three minutes to meet time!

Wu Tianzhen said: When the people arrived, we went to the "car dou", a group of 12 drivers, and went to the garage in the store.

It turned out that Huang Qiang was already in the conference room of "Che Dou", but this conference room had an extra mobile whiteboard and a few colored pens for the whiteboard.

Huang Qiang habitually cleared his throat first and then said: Ladies and gentlemen, let me introduce a new comrade-in-arms to everyone, and he is also the last member of our T15 group, his name is Zhang Yuan. Ah Yuan, do you have an English name, or an alias?

Zhang Yuan said shyly: People in the school joke that I make "strong gold steel legs", and you call me like this... It seems a little long!

Huang Qiangdao: He is the representative of the county's sprint team, I call you Ah Yuan, just a name, easy to read and remember, our team members are all people who want to win the championship, and we can get more glory and bonuses for the "strongest bicycle shop", which is our purpose, you know? Children!

Huang Qiang continued: Ah Yuan, you are the first day to participate in our training camp, after a few training camps, let's take a look at your performance together, okay, let's talk back to our theme today.

In this province, there are bicycle races and provincial team leagues held every month, so there are many bicycle enthusiasts who sign up for team competitions.

At present, it is Guangdong Province alone, and there are more than 2,000 full-time and part-time riders alone. In the past, it was impossible to be a cyclist and be able to prosper, but now in a commodity economy, whoever is more professional and hard-working, the greater the chance of fame and fortune, and the more benefits.

Ah Yuan, from today onwards, every Saturday afternoon and Sunday, we will have a cycling team drill, including roads, mountains, mud, cross-country, city streets, sharp bends and other different environments, we all have to face and overcome. After that, follow the instructions of your team leader, SAM.

Sam patted Zhang Yuan's arm kindly at this time and said: Ah Yuan, don't be nervous, we are the same team, our team is Team Work, there is no personal heroism, everything is based on the team's results as the primary task, as long as you do a good job of cooperation and division of labor, it is not difficult to win the game.

You don't know how good Brother Tianzhen is, they have won a lot of championships by teamwork, and they have won a lot of championships in T15 and T18, so he can be my father's assistant and take care of the "strongest bicycle shop".

Huang Qiang said: Sam, nonsense novel, let's have a three-group competition today, and still follow the old rules.

Zhang Yuan asked: What are the old rules?

Ah Xing interjected: Even on the same track, the total time of 4 people in the T21 group is 1 minute less than the total of 4 people in the T18 group, and 2 minutes less than the total of 4 people in the T15 group

Da Jiu also said: If the total time of T21 is less than 3 minutes of T15, it means that T15 group loses to T21, and if the total time of T21 is more than 2 minutes, it means that T21 loses the group match.

Zhang Yuan felt very interesting when he heard such competition rules, and at the same time, he also wanted to understand his true strength and the nature of the competition that he began to get used to the cooperation and division of labor among everyone.

In the summer, the Heping Mountains are full of yellow rape fields, and around these rape fields are the twists and turns, narrow bicycle paths, and some mountain roads, covered with small gravel and muddy roads.

The area with beautiful scenery and fresh air, but the road conditions are bad, and the "Jinchong" team, the "strongest bicycle shop", is the main venue for daily training, and only under the most arduous training can they have the best physique and experience to deal with the best opponents in the world without fear.

The high temperature of the summer afternoon and the high-altitude and low-oxygen competition environment in the mountainous area will definitely help the team members to improve their physical fitness (lung capacity) during the training process. Each race bike is the private property of each contestant to assemble and maintain by himself, except for one person, that is, Zhang Yuan, his bicycle, just by the store to take out the use of high-end brand race bicycles, all aspects of the performance of this bicycle, are not Zhang Yuan satisfied.

Fifteen minutes before the practice match, Sam was discussing with the three members of the group, Zhang Yuan, Ah Man and George. Since it was the first time to meet and make contact, Sam raced in a more conservative and steady way, starting with George as the first section of the lead car, adding a glass on the flat road, trying to keep the distance (with T21 and T18) within 3 seconds, and the distance between each team member should not exceed 1 second;

The second section of the pure uphill mountain road, I (Sam) is in charge, the goal is to distance within 12 seconds, and the distance of the group members is 3 seconds;

The third section is in charge of Zhang Yuanlai, going down the hill and hairpin bend, the target distance is 14 seconds, and the team member distance is 3 seconds.

The last section is in charge of Aman, rushing the last 500 meters, speeding up by half a second on average, so that the target distance is within 20 seconds, and the distance between the team members cannot exceed 5 seconds.

At the beginning of the game, there was no suspense in the T21 group of 4 people, who took the lead at the beginning, and the wind was broken by Wu Xiaoge; Naturally, it was the T18 team members who were in hot pursuit, but George was not bad, only 0.25 seconds away from Zhu Zai, who was in the last place in T18, and it seems that the T15 strategy was effective.

After that, in the second section, it was Sam who relayed George, Sam came to lead the same group of 4 people up the hill, due to the limitations of height and physical strength, obviously, T18 was dragged farther and farther away by the opponent, the second section was not halfway, and the distance from T18 has been opened for more than 10 seconds, and Zhang Yuan's specialty is to walk the mountain road, so he has been close to Sam.

At the end of the second paragraph, there was a difference of 17 seconds with T21, and a difference of 2.5 seconds between the members of T18.

The third section of downhill, there is nothing special to describe, except for a very particular hairpin-shaped detour, for Zhang Yuan, this bend is too simple, this section is led by him, and the previous two groups are chasing nearly 2 seconds faster.

In the fourth stage, Ah Man came up to take over the last sprint, and it was originally Ah Man's strong point to run wild on the flat road on the bike, and he chased 1.5 seconds faster, which was a good result.

In the end, the T21 group was 1 minute and 7 seconds faster than the T181 group, and 2 minutes and 12 seconds faster than the T15 group...

Huang Qiang's instructions: Today, everyone's level is good, especially Ah Yuan, who has a good performance in the first training camp, come on!
