Benar om mt, untuk saat ini Keirin termasuk salah satu kategori track racing di UCI, namun Keirin di Jepang dan di kejuaraan Internasional punya perbedaan, paling mencolok, sepeda yang dipake balapan Keirin kategori UCI belum tentu bisa digunakan untuk balapan Keirin di Jepang (tidak ada NJS Stamp)
Terus terang, bukan karena Keirin berasal dari Jepang yang bikin saya suka hal ini, tapi karena...."Cuman track sekarang udah pindah ke sepeda carbon, keirin masih tradisional aja."
Old School from beginning until now, wkwkwkwkkw
Ayolah om yos, om yos jadi lokomotifnya track bike di C-Id, kalo di Road Bike kan udah ada om mt dan teman-teman lainnya
haha..jangan saya Om D..
saya masih beginner soal beginian..
Keirin Bike's Weight
monster track berkedok domba kalo situ om
saya aja keracunan fixie gara-gara om yos
The Rules in Keirin
The intense battles between cyclists is what makes keirin races so exciting. But there is always the danger of cyclists going too far and causing major accidents that could disrupt the race. Keirin therefore has strict rules, and heavy penalties are imposed on violators. Cyclists disqualified for a major violation during a race are stripped of their finishing position in that race, heavily impacting their performance record. (Disqualification is the most severe penalty imposed for rule violations.)
The violator forcibly cuts across diagonally into another line.
The violator cuts into the path of an opponent from the inside.
The violator overtakes a leading opponent on the inside, when the opponent is not in the outermost lane.
The violator forces an opponent toward the outer edge of the track.
1. Backstretch line
A line on the backstretch exactly one half lap from the finish line. The cyclist who crosses this line first adds one to their B (number of backstretch leads) count.
2. Yellow line
The yellow line 3 meters inside the inner line.
3. Outer line
The outer of the two lines inside the bank.
4. Inner line
The inner of the two lines inside the bank.
5. Side line
The flat brown portion of the track inside the inner line. Cyclists ride here to leave the race.
6. Homestretch line
A line on the home straightaway of the bank. Also serves as the finish line. The cyclist who first crosses the homestretch line with just one more lap to go adds one to their H (number of homestretch leads) count.
7. 30-meter line
A line on the bank (race lanes), 30 meters before the finish line. Cyclists who fall after crossing this line on the final lap are permitted to finish even if they have to carry or push their bicycles across the finish line.
8. 25-meter line
A line 25 meters from the starting line. After the starter's pistol has been fired, the race can be restarted if a problem is judged to have occurred before the cyclists have reached this line.
The Phases of a Keirin Race
The warmup is an important information gathering opportunity for bettors. Before the start of the race proper, the competitors enter the track and warm up by riding around the banks. This is a time for cyclists to show off their abilities and decide who will be in each line, so should not be dismissed as a mere preamble. Use the warmup to carefully examine the makeup of each line.
Once betting has closed, the rear wheels of the bicycles are attached to the starting blocks, then all the competitors start simultaneously at the sound of a starter pistol. At first the cyclists ride behind a pacer in the front. (Cyclists try to gain the position that best suits them by comparing their own performance characteristics to those of the other competitors, and considering factors such as wind direction, wind speed and bank radius. Seeing whether each cyclist can gain their desired position is the highlight of a race opening.)
To minimize the wind resistance on the competitors, a pacer rides in front as a windbreak up to a predetermined position on the track.
(The number of laps varies with each race. The number of laps remaining in the race is indicated by the lap indicator next to the finish line. Blue means three laps remaining; red means two.)
4. Bell or gong
A bell or gong sounds when the lead cyclist crosses the backstretch line one-and-a-half laps away from the finish line. At the sound, the race starts to reach its climax and the pace picks up.
5. Finish line
On the final straightaway, cyclists form a pack as they race toward the finish line at speeds approaching 70 kilometers an hour.
A Day at Keirin School
Those who want to become professional keirin cyclists must go to a special keirin school and make it through the demanding training course. See what life is like for these would-be keirin cyclists below.
6:45 to 7:40 am
Roll call, drills and morning cleaning. After waking up, students have 15 minutes to get ready before roll call. After roll call, it's time for exercises and running known as drills, followed by morning cleaning duty. Mornings are a busy time for students.
7:40 to 8:10 am
Breakfast. Since the students will train hard all day, they eat about twice what the average person eats for breakfast—a meal of around 1,300 calories.
9:05 to 9:50 am
1st period: Hill climbing. The most notorious type of keirin school training. This demanding exercise calls for students to cycle up gradients of 14 degrees—a steepness the average person wouldn't be able to budge an inch on.
9:55 to 10:40 am
2nd period: Lap training. Training designed to improve group racing skills. Also features exercises where bikes are towed to let cyclists experience speeds past their limits and improve their pedal power.
10:45 to 11:30 am
3rd period: Lap training
11:30 am to 12:30 pm
12:40 to 1:25 pm
4th period: Science class. Keirin school is not all about bicycle training. Students also learn the knowledge they will need after their professional debut, such as race rules and training theory.
1:30 to 2:15 pm
5th period: Science class
2:25 to 3:10 pm
6th period: Roller training. Training on rollers the average person would find almost impossible to ride. Used mainly to improve balance.
3:20 to 4:05 pm
7th period: Race training. Training that simulates actual races to give students the feel of actual events.
4:15 to 5:00 pm
8th period: Race training
5:30 to 7:10 pm
Bath time. Students hit the baths to relax at the end of an exhausting day.
5:45 to 6:45 pm
Dinner. Physically drained by the colossal energy expenditure needed for the day's grueling training, students refuel with a massive meal at the end of the day.
They pile on the calories to prepare for the next day's challenges. Keirin school students consume about 4,500 calories per day.
10:00 pm Lights out
Track cycling: Keirin uncovered
My money is on Mr Green with the huge thighs. The pacer winds his thing up and peels off. Mr Black goes for it, opening up a gap. For as long as I can remember I’ve wanted to go to Japan to watch a keirin race.
Approaching the arena entrance, it becomes abundantly clear that this is no ordinary track race. The scene is awash with scruffy old men smoking and coughing, and it is more like entering a dog racing track than anything else. As I enter a huge great courtyard, this impression is reinforced further. I am confronted by hack-like figures in hats and scruffy suits, wide boys with bleached hair and chains, and toothless old ladies scurrying around. Betting slips litter the ground like huge snow flakes, and it is totally clear that these guys wouldn’t know their Lance Armstrong from their Red Rum.
As they huddle around overhead TV screens watching replays of the action, a strange ping pong sound echoes around the area. This heralds the start of the next round of races, and the crowd hurry off in the direction of the track. Not knowing what else to do, I follow. The racing is about to begin and I wander around in total amazement. Great high rise terraces surround the sides and ends of the velodrome, and gamblers are literally crammed into the seats there. Groups of punters huddle together comparing odds and checking their betting slips, eagerly waiting for the riders to emerge.
The velodrome looks like something out of a fifties American gambling movie, with a massive hard-surfaced open track surrounded by high fences, and corner towers for the flag-wielding judges to analyse the action. Wheeled iron stretchers lay in wait on the corners, and serve as a testament to the extreme physical nature of the sport. There’s a sky-high pole with a TV camera perched on top standing proudly in the centre of the track. This captures footage of the racing, which is not only screened to the massive TVs within the arena, but to off-site gambling establishments and live on the internet.
As the tannoy continues, young uniformed boys run around waving flags. Other youngsters clear and check that the track is ready for the action. The tension is slowly building, but in true Japanese style, the noise levels are deceptively calm and subdued. The pacer is the next figure to emerge. In Japanese keirin there is no motorbike, and a keirin racer is paid to ride as a lead pacer instead. On the far side of the track I can just about make out a line of coloured blobs, the racers. A whistle blows, and one by one they walk on to the track, bow to the crowd and head towards the starting blocks. It is just as I’d imagined, only better.
The racers ride a standard retro-style bike: there’s no carbon fibre frame or disc wheels here. These bikes are regulation steel frames, spoked wheels and toe straps (so that they are easily repairable, and make everything fair for the gambling). Each rider has his race colours and number, and they all look huge – this is mainly due to their dustbin lid helmets and body armour, although the thighs on some of these guys are outrageous.
To all but the well initiated, the riders are anonymous and their colours and odds determine the betting form rather than marking out individuals. Being a keirin star in Japan means that you can earn up to $2million a year. However, unlike other popular sports, the keirin racers are not seen as heroes, and due to the demands of a heavy race schedule, hardly ever get the chance to compete in regular track events.
On the track the greyhound-like riders are slotted into the starting gates and bow one final time to the crowd – good mannered to the last. The pacer mounts up and the race begins. The action is slower and more tactical than international keirin races, penalties apply for bad riding and as a result accidents are far less common. Plus the riders are under an immense amount of pressure from the gamblers.
Mr Pink takes a tumble…
The race is well and truly on and you can see each rider’s tactics unfolding before your eyes. (Unlike any other sport in the world, riders have to state their tactics to officials before the race, and it is the job of the other riders to prevent them playing these out – foul play is very dishonourable, and can lead to suspension). There’s a real tussle right to the line. Mr Black is pulled back. Mr Pink takes a fall and Mr Blue just about manages to secure victory. There is no arm waving or victory celebrations, such things are not permitted, just heads down and backs to the wall. The crowd reacts similarly, with sighs and groans but no shouting, cheering or swearing.
As the riders leave the track, an almost identical-looking bunch of riders enter it and circle around like horses so that you can look them over and judge your form for the next race. Then it’s back to the betting office. As you can probably gather, keirin is massively popular in Japan and it’s all about the gambling. Keirin race meets take place at velodromes throughout the country on most weeks, meetings generally last for about three days, and depending on the grading, there are between eight and eleven races each day.
Back to school
Less than 24 hours after experiencing my first keirin tournament, I am on a bullet train heading across Japan towards the world famous, but highly guarded keirin school. It has taken months of work, vetting and applications to enable me to visit the school, so it’s a rare privilege. Driving through rain storms and clouds we head into the hills beneath the fabled Mount Fuji. I imagine that my visit will be a waste of time – after all, rain stops play as far as track racing is concerned – but as I discover, this rule doesn’t apply in Japanese keirin racing and training. Unless there is snow on the track, the students will be training.
The whole thing is mind-blowing and hard to take in. The campus covers a vast expanse in the hills. There are three different velodromes, a road circuit, and a straight line sprint road with a steep hill at the end of it. This is designed to be ridden at full whack on a fixed wheel (after a 200m sprint). There is also a huge spinning-style gym, a massive mirrored roller riding room, a huge gymnasium, laboratories, class rooms, mechanical workshops, dorms, offices and dining rooms. It looks like a cross between a university and an army camp, and it’s gigantic!
Making the grade
Every year the school accepts 75 students aged between 17 and 29. There are more than 1,000 applicants each year, and selection is based on a number of criteria. The first is the ability to ride a kilometre in under 1min 10s, and a flying 200m in under 12.8s. Then you need to pass various academic exams. This is often the stumbling block for most of the ‘physical’ riders. There’s as much emphasis on the academic side as the physical. Because of this, the school accepts five ‘non-cycling’ students each year. This means that those with great academic qualifications who can make a minimum height in a squat jump can be accepted. The only other exceptions to the standard rule are those with Olympic or championship medals.
The students spend a whole year at the school, and their days are split between physical and academic training. They all live in small dorm rooms, are allowed one personal photo on their desks, get up at 6.30am and go to bed at 10pm. Mobile phones are banned here, and weekend passes are only earned by the top students. It really is boot camp with an added dose of discipline.
As well as basic education, the riders are educated in the art and theory of keirin racing – and gambling. Graduation only takes place after achieving set cycling standards, passing exams, and ultimately an interview – to assess mental strength and temperament. Few fail the procedure, and those that do have the opportunity to re-enter the school the following year.
My escorted tour is truly strange and fascinating. Although the rain is hurling down, riders are still lining up regimentedly for their afternoon track session. I am allowed to look around for a while, and even climb the tower above the roller room, which is used by the coaches to administer their commands. A few riders pedal away, with their every move scrutinised by one of the 12 on-site bike coaches. While this is taking place, other students pound the tracks outside, splashing through the rain and reacting to every megaphone demand of the coaches. A couple of others have affixed a rear brake to their bikes and are headed towards the torturous road session. This is seriously disciplined stuff, yet it seems to work.
Edited, from here
kalo ajang seperti keirin ini di aplikasikan di indo bakal pro/kontra kali ya..dari pada sepedaaan dijalan raya taruhan nya nyawa atau waktu main cuma subuh-pagi/midnight(nightrider)..
As long ga ada unsur judinya, model olahraga kaya keirin Jepang IMHO baik untuk diterapkan.
Ada sekolahnya, ada jenjangnya dan tournament rutin setiap tahun.
Cyclist belajar disiplin dan tidak tergantung pada teknologi dan modal uang (semua sepeda harus standar dan punya spek yang hampir sama). Cukup fair buat saya.
Sisi judi-nya memang jadi downside buat saya, tapi saya seneng belajar tentang Keirin karena salah satu konsep di atas. Kesederhanaan.
keren om Dx info nya
Thank you om Yos..
tambahin lagi dong infonya....
Klo yg ini cuma foto2 sekumpulan "penikmat" frame-frame NJS aja, yang tadi pagi kumpul di CFD Sudirman berlanjut ke Taman Menteng
damn tuh paha.....
chainring berapa ya ? 53 kali ya...
Biasanya ch 53t om andy, yang belakang dipilih sesuai kemampuan rider, rata- rata 11-15
Biasakan sejak dini...
Sepertinya ada yg mulai keracunan part NJS niiiiih...
