The characteristics of mountain bikes are obvious, compared to road racing, mountain bikes have wider and thicker tires, and the tires are covered with uneven rubber particles to cope with the complex and varied mountain conditions. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In addition to mountain tires, there is one part that must also be fitted to a mountain bike, and that is the shock.

Almost every mountain bike is equipped with a suspension fork, which is colloquially known as a hardtail. XC racing cars also usually have rear shocks, which are bikes with shock absorbers installed in the front and rear, commonly known as soft tails.

The common name of hard tail and soft tail is very vivid, and the hard tail bike with only a suspension fork will feel a clear sense of wheel vibration when riding in the mountains, and the soft tail bike with full suspension will bring the rider a more gentle feeling when riding. If you go to a mountain race without a shock absorber, your balls will definitely be shattered.

After a lot of selection, Duke chose a Marin-mount competition-grade XC mountain bike as his crotch mount.

The frame of this Marin is made of aluminium and painted in chocolate. Its suspension fork is short-travel XC, and the rear shock is an oil-and-gas type.

Compared with the glamorous field cars and TT cars, mountain bikes are rough old men, but only rough rough old men can adapt to the harsh wild environment, and the glamorous girls will explode in less than a few minutes when they go to the barren mountains and mountains.

The bike was chosen, and Duke pushed the bike outside, rode all the way to the mountain cross-country training ground, and began to test drive.

The mountain cross-country track in the Chenggong training base has a total length of 3,025 meters, with uphill and downhill sections, sand sections, wading sections, mud sections, stone sections, gravel sections, steps, bridges, woodland sections and other road sections, which fully meet the track setting standards of the Olympic Games, World Championships and Continental Championships.

The only drawback is that the track at the Chenggong Training Ground is slightly shorter, only 3 kilometers and more than 25 meters.

The XC mountain course in the official race is between 4.5~5.5 kilometers in length, and the riders ride around the track for 7 to 8 laps, usually between 30~45 kilometers.

The track map for the Rio Olympic mountain race has been released, with a 4.85-kilometre circuit and seven laps for a total of 33.95 kilometres.

The difference between the length of the Chenggong track and the Rio track is nearly 2 kilometers, but there is no way, so let's practice first. For every 1 km of the training track of the mountain race, the expansion cost and daily maintenance cost are as high as more than 10 million yuan, and the Chenggong training track is already the best mountain track in China in terms of road section setting.

For the rest of the day, Duke and his only mountain teammate, Wang Zhen, cycled around the training track every day, each riding an average of about 20 laps a day.

About Du Ke, Director Zhu has surprise discoveries every day. After a few days of running at less than 15 km/h, Douc was fully familiar with the track and had reached speeds of 20 km/h.

By the end of April, Duke's speed on this training track had stabilized at 23~25 km/h.

In mountain racing, to be able to stabilize at this speed is world-class.

The top 50 mountain riders in the world are able to maintain their speeds of around 20 km/h on any course. At 22.5 km/h, this is the level of the top 20 in the world. At 25 km/h, that's at least one of the top five in the world.

"Du Ke, you're too hanging...... " After today's training, Wang Zhen said to Du Ke in disbelief but had to be convinced.

Wang Zhen is 26 years old and a rookie mountain racing rookie who has emerged in recent years. 26 is a relatively young man for a mountain biker, and of course, 22-year-old Duke is even younger. Wang Zhen is traveling at around 16~18 km/h on this training track, and he is currently ranked 165th in the world.

Based on the 33.95-kilometer length of the Rio circuit, Wang Zhen will complete the race in 1 hour and 53 minutes at the earliest, while Du Ke will be able to complete the race in 1 hour and 28 minutes at the latest.

The same track, 25 minutes of time difference, this is probably the gap between the international top drivers and the Chinese top drivers, if you set the ring, Du Ke can set Wang Zhen for several laps.

"After all, this is just training, we are playing on one track, and when we go to the official competition, we have to compete with forty or fifty foreign players, which is different." Duke looked more rational and calm.

For this reason, the total number of registrations for the men's cycling mountain race at the Rio Olympics is 44, and if Du Ke and Wang Zhen win the championship and runner-up in the Asian Championships, and they get tickets to Rio at the same time, then they will face the challenge of 42 other foreign athletes at the Rio Olympics.

A group of people going around in circles and two people playing at the same time, of course, is different. If Douc doesn't take the lead as soon as he starts, he won't be able to go faster in the official race than he did in training, and in some tight sections of the mountain race, with other riders stuck in front of Doucle, overtaking is almost impossible to do, and he has to follow.

The top 50 mountain race runners in the world are able to maintain their speeds of around 20 km/h on any course...... The subject of this sentence is the top 50 masters in the world, the first keyword is "any track", and the second keyword is "20 km/h".

In any race, in any track, a rider who can ride a stable speed of more than 20 km/h is a master.

It's useless to play alone in training, to be alone and alone.

"Director Zhu, do you have to pull up the team and take me and Wang Zhen out to practice? It is best to be able to compete with international drivers and find gaps in actual combat, which is the most effective way to test the results of training. Du Ke asked Director Zhu that he had to go to some official mountain races and test the water, otherwise he would go directly to Malacca to participate in the Asian Mountain Bike Championships, and Du Ke didn't know the bottom of his heart.

Coach Zhu nodded: "That's a must, from May to July, it is the peak season of mountain biking, there are many events in Europe and the United States, and an international mountain bike event recognized by UCI will be held every few days on average." It's said that you're going to the Diamond League in track and field in May, so we're going to have a meeting, with the track team, to work out your training and competition schedule for the next few months. ”

The special coaching staff specially set up for Du Ke by the track and field national team was also at the Chenggong base, so half an hour later, Du Ke, the cycling team, and the track and field team held a meeting together.

According to the schedule of athletics, cycling, including swimming and other events from May to August, everyone finally came to a consensus:

From the end of April to May 14, Du Ke continued to stay at the Chenggong base, cycling training and track and field training, during this time, track and field mainly practiced two individual events, long jump and 400 meters.

On May 15, Duke left the base and flew to Huhai to prepare for the 2015 Diamond League Shanghai, where he will compete in two individual events, the long jump and the 400m.

In the 400m, Duke had enough IAAF points to sign up, and he was the overall champion of last year's Diamond League 100m, 400m, 800m and high jump, while losing to Usain Bolt by a few points in the 200m. The long jump is a wild card to participate in the Shanghai Station competition, and in this Diamond League held in my country, the wild card is a small case.

After that, Duke will fly to the United States to participate in the two Diamond Leagues held in Eugene and New York on May 30 and June 13, and brush up on the 100m, 200m and high jump. It is estimated that he will only be able to participate in the three Diamond Leagues in Shanghai, Eugene, and New York this year, and then he will have to prepare for the World Swimming Championships in Kazan and the World Athletics Championships in the capital of China.

After the Diamond League in New York, Duke will remain in the United States to participate in the Ohio International Mountain Bike Invitational on June 16 in Ohio, USA.

For people like Duke who don't have a UCI point, it's not difficult to participate in a commercial invitational tournament, just pay money to buy an invitation card.

Commercial events with words such as "invitational tournament" and "challenge", as long as enough money is produced for a Chinese company to sponsor it, properly engage in public relations, and buy a ticket is too easy, and the commercial event is not just to make money. For events with words such as "World Championships" and "Olympic Games", you can't buy tickets with money, so you can only rely on your strength to grab tickets.

After Duke returned from the United States, it was almost late June, and by that time he had to report to the swimming team to prepare for the World Swimming Championships in Kazan. Around mid-to-late July, Doucle will arrive in Kazan, Russia, with the swimming team, to adapt to the local environment, and officially start participating in the World Championships swimming events on August 2.

All in all, Duke's schedule has been so full in recent months that he can't wait to split one day in half for two days. (To be continued.) )
