Task: Question Answering
Input (English): Context: Cycle sport is competitive physical activity using bicycles. There are several categories of bicycle racing including road bicycle racing, time trialling, cyclo-cross, mountain bike racing, track cycling, BMX, and cycle speedway. Non-racing cycling sports include artistic cycling, cycle polo, freestyle BMX and mountain bike trials. The Union Cycliste Internationale (UCI) is the world governing body for cycling and international competitive cycling events. The International Human Powered Vehicle Association is the governing body for human-powered vehicles that imposes far fewer restrictions on their design than does the UCI. The UltraMarathon Cycling Association is the governing body for many ultra-distance cycling races., The rainbow jersey is the distinctive jersey worn by the reigning world champion in a bicycle racing discipline , since 1927 . The jersey is predominantly white with five horizontal bands in the UCI colours around the chest . From the bottom up the colours are : green , yellow , black , red and blue ; the same colours that appear in the rings on the Olympic flag . The tradition is applied to all disciplines , including road racing , track racing , cyclo - cross , BMX , Trials and the disciplines within mountain biking . The jersey is produced by Santini SMS since 1994 . A world champion must wear the jersey when competing in the same discipline , category and speciality for which the title was won . For example , the world road race champion would wear the garment while competing in stage races ( except for time trial stages ) and one - day races , but would not be entitled to wear it during time trials . Similarly , on the track , the world individual pursuit champion would only wear the jersey when competing in other individual pursuit events . In team events , such as the team pursuit , each member of the team must wear the rainbow jersey , but -- again -- would not wear it while racing in , say , points races or other track disciplines . The rainbow jersey helps make a world champion easier to spot for spectators , but it also has the effect of making the title - holder more visible to other competitors , particularly in road racing situations . This can be a disadvantage as it makes it more difficult for the world champion to launch an attack , while other riders will quickly seek to take advantage if they notice the rainbow jersey crashes or suffers a mechanical or other problem . There is also reduced space for sponsors ' logos on the world champion 's jerseys ; however , the increased media coverage of a reigning world champion probably offsets the effects of the smaller logo space . Failure to wear the rainbow jersey where required carries a penalty of 2500 to 5000 Swiss francs . After the end of a rider 's championship year , they are eligible to wear piping in the same rainbow pattern on the collar and cuffs of their jersey . They retain this right for the remainder of their career . If the holder of a rainbow jersey becomes leader of a multi-stage race ( such as the Tour de France ) then the leader 's jersey ( Yellow jersey ) for that race takes precedence . Similarly , the leader 's jerseys for UCI World Cup series also take precedence over the rainbow jersey , although , in 2006 , Road Race World Champion Tom Boonen at one point was the leader of the Road Racing World Cup , and he , as well as his sponsor and the organizers of the race he was competing in at that time ( Gent -- Wevelgem ) wanted him to continue wearing the rainbow jersey . A compromise was reached and Boonen wore a jersey which was a combination of the Rainbow jersey and the UCI World Cup jersey ., The Netherlands  is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three island territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing maritime borders with Belgium, the United Kingdom, and Germany. The largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague and Utrecht. Amsterdam is the country's capital, while The Hague holds the Dutch seat of government and parliament. The name "Holland" is used to refer informally to the whole of the country of the Netherlands., Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits. The sport evolved from motorcycle trials competitions held in the United Kingdom., Mountain biking is the sport of riding bicycles off-road, often over rough terrain, using specially designed mountain bikes. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain., A BMX bike is an off-road sport bicycle used for racing and stunt riding. BMX means bicycle motocross., A mountain bike or mountain bicycle (abbreviated Mtn Bike, MTB; or ATB, for all-terrain bicycle) is a bicycle designed for off-road cycling. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. These typically include suspension on the frame and fork, large knobby tires, more durable heavy duty wheels, more powerful brakes, and lower gear ratios needed for steep grades with poor traction., BMX racing is a type of off-road bicycle racing. The format of BMX was derived from motocross racing. BMX bicycle races are sprint races on purpose-built off-road single-lap race tracks. The track usually consists of a starting gate for up to eight racers, a groomed, serpentine, dirt race course made of various jumps and rollers and a finish line. The course is usually flat, about wide and has large banked corners that help the riders maintain speed. 
The sport of BMX racing is facilitated by a number of regional and international sanctioning bodies. They provide rules for sanctioning the conduct of the flying, specify age group and skill-level classifications among the racers, and maintain some kind of points-accumulation system over the racing season. The sport is very family oriented and largely participant-driven, with riders ranging in age from 2 to 70, and over. Professional ranks exist for both men and women, where the age ranges from 18 to 40 years old., Freestyle BMX is bicycle motocross stunt riding on BMX bikes. It is an extreme sport descended from BMX racing that consists of five disciplines: street, park, vert, trails, and flatland., BMX, an abbreviation for bicycle motocross, is a cycle sport performed on BMX bikes, either in competitive BMX racing or freestyle BMX, or else in general on- or off-road recreation. BMX began when young cyclists appropriated motocross tracks for fun, racing and stunts, eventually evolving specialized BMX bikes and competitions., Cyclo-cross (sometimes cyclocross, CX, cyclo-X or cross) is a form of bicycle racing. Races typically take place in the autumn and winter (the international or "World Cup" season is OctoberFebruary), and consist of many laps of a short (2.53.5  km or 1.52  mile) course featuring pavement, wooded trails, grass, steep hills and obstacles requiring the rider to quickly dismount, carry the bike while navigating the obstruction and remount. Races for senior categories are generally between 30 minutes and an hour long, with the distance varying depending on the ground conditions. The sport is strongest in the traditional road cycling countries such as Belgium (Flanders in particular), France and the Netherlands., Subject: rainbow jersey, Relation: sport, Options: (A) bicycle motocross (B) cycle sport (C) cycling (D) motocross (E) mountain biking (F) polo (G) road bicycle racing (H) road cycling (I) sport (J) united kingdom
