Peloton La Mongie RDS 2012
In a road bicycle race, the peloton (from French, originally meaning 'platoon') is the main group or pack of riders. Riders in a group save energy by riding close ( drafting or slipstreaming) to (particularly behind) other riders. The reduction in drag is dramatic; riding in the middle of a well-developed group, drag can be reduced to as little as 5%–10%. Exploitation of this potential energy saving leads to complex cooperative and competitive interactions between riders and teams in race tactics. The term is also used to refer to the community of professional cyclists in general. Definition More formally, a peloton is defined as "two or more cyclists riding in sufficiently close proximity to be located either in one of two basic positions: (1) behind cyclists in zones of reduced air pressure, referred to as ‘drafting’, or (2) in non-drafting positions where air pressure is highest. Cyclists in drafting zones expend less energy than in front positions." A peloton has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accordion Effect
In physics, the accordion effect, also known as the slinky effect, concertina effect, elastic band effect, and string instability, occurs when fluctuations in the motion of a travelling body causes disruptions in the flow of elements following it. This can happen in road traffic, foot marching, bicycle and motor racing, and, in general, to processes in a pipeline. These are examples of nonlinear processes. The accordion effect generally decreases the throughput of the system in which it occurs. In traffic The accordion effect in road traffic refers to the typical decelerations and accelerations of a vehicle when the vehicle in front decelerates and accelerates. These fluctuations in speed propagate backwards and typically get bigger and bigger further down the line, resulting in reduced throughput of road traffic. For this reason, the Norwegian Public Roads Administration recommends that each driver should try to follow the accelerations of the vehicle in front closely, and k ...

Road Bicycle Racing
Road bicycle racing is the cycle sport discipline of road cycling, held primarily on Road surface, paved roads. Road racing is the most popular professional sport, professional form of bicycle racing, in terms of numbers of competitors, events and spectators. The two most common competition formats are mass start events, where riders start simultaneously (though sometimes with a Handicapping, handicap) and race to a set finish point; and time trials, where individual time trial, individual riders or team time trial, teams race a course alone against the clock. Stage races or "tours" take multiple days, and consist of several mass-start or time-trial stages ridden consecutively. Professional racing originated in Western Europe, centred in France, Spain, Italy and the Low Countries. Since the mid-1980s, the sport has diversified, with races held at the professional, semi-professional and amateur levels, worldwide. The sport is governed by the Union Cycliste Internationale (UCI).

Sprinter (cycling)
A sprinter is a road bicycle racer or track racer who can finish a race very explosively by accelerating quickly to a high speed, often using the slipstream of another cyclist or group of cyclists tactically to conserve energy. Apart from using sprinting as a racing tactic, sprinters can also compete for intermediate sprints (sometimes called ''primes''), often to provide additional excitement in cities along the route of a race. In stage races, intermediate sprints and final stage placings may be combined in a points classification. For example, in the points classification in the Tour de France, the ''maillot vert'' (green jersey) is won by the race's most consistent sprinter. At the Tour de France, the most successful recipient of this honor is Slovak sprinter Peter Sagan, who has won seven Tour de France green jerseys (2012–2016, 2018–2019). The road sprinter Sprinters have a higher ratio of fast-twitch muscle fibers than non-sprinters. Road cycling sprinters sometime ...

Breakaway Specialist
In bicycle racing, a breakaway specialist is a rider who is specialized in attacking the race from the start in order to show off their sponsor and to try their luck in winning the stage without having to fight with the whole peloton at the finish line. The French term for a breakaway specialist is baroudeur or adventurer, which comes from the Arabic, where its meaning is “dynamite” Details Examples of such racers include Thomas De Gendt, Jens Voigt, Thomas Voeckler, Alessandro De Marchi, Tony Martin, Sylvain Chavanel, Sandy Casar, Pierrick Fédrigo, Luis León Sánchez, Jérémy Roy, Steve Cummings, Lilian Calmejane, Jacky Durand, and Franck Bonnamour. Cyclists who regularly participate in breaks are typically neither particularly fast climbers nor sprinters, and getting in a break offers their best chance of winning the stage or race. While many riders will occasionally take part in breaks, the most prominent breakaway specialists are known for the frequency of their a ...

Echelon Formation
An echelon formation () is a (usually military) formation in which its units are arranged diagonally. Each unit is stationed behind and to the right (a "right echelon"), or behind and to the left ("left echelon"), of the unit ahead. The name of the formation comes from the French word échelon, meaning a rung of a ladder, which describes the shape that this formation has when viewed from above or below. Military formation Use of the formation dates back to ancient infantry and cavalry warfare, as an alternative to column, line-abreast, or phalanx (box) formations. One of its earliest uses was at the Battle of Leuctra, when the Thebans attacked the Spartan right with a column 48 men deep while their weaker center and right were repelled. The echelon formation may have been used by Hannibal at the Battle of Cannae, Alexander the Great at the Battle of Gaugamela, Frederick II of Prussia, and the Confederate army at the Battle of Gettysburg. The tactic still persists and is reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crosswind
A crosswind is any wind that has a perpendicular component to the line or direction of travel. This affects the aerodynamics of many forms of transport. Moving non-parallel to the wind's direction creates a crosswind component on the object and thus increasing the apparent wind on the object; such use of cross wind travel is used to advantage by sailing craft, kiteboarding craft, power kiting, etc. On the other side, crosswind moves the path of vehicles sideways and can be a hazard. Definition When winds are not parallel to or directly with/against the line of travel, the wind is said to have a crosswind ''component''; that is, the force can be separated into two vector components: * the headwind or tailwind component in the direction of motion, * the crosswind component perpendicular to the former. A vehicle behaves as though it is directly experiencing a lateral effect of the magnitude of the crosswind component only. The crosswind component is computed by multiplying the win ...
