Criterium
A criterium, or crit, is a bike race consisting of several laps around a closed circuit, the length of each lap or circuit ranging from about 400 m to 10,000 m. Overview Race length can be determined by a number of laps or total time, in which case the number of remaining laps is calculated as the race progresses. Generally the event's duration (commonly one hour) is shorter than that of a traditional road race — which can last many hours, sometimes over the course of several days or even weeks, as in a Grand Tour. However, the average speed and intensity are appreciably higher. The winner is the first rider to cross the finish line without having been "lapped". Events often have prizes (called ''primes'' and are usually cash) for winning specific intermediate laps (for instance, every 10th lap). A bell is usually rung to announce to the riders that whoever wins the next lap will be awarded the prime. Success in road criteriums requires a mix of good technical ski ...

Tour De France
The Tour de France () is an annual men's multiple-stage cycle sport, bicycle race held primarily in France. It is the oldest and most prestigious of the three Grand Tour (cycling), Grand Tours, which include the Giro d'Italia and the Vuelta a España. The race was first organized in 1903 Tour de France, 1903 to increase sales for the newspaper ''L'Auto'' (which was an ancestor of ''L'Équipe'') and has been held annually since, except when it was not held from 1915 to 1918 and 1940 to 1946 due to the two World war, World Wars. As the Tour gained prominence and popularity, the race was lengthened and gained more international participation. The Tour is a UCI World Tour event, which means that the teams that compete in the race are mostly UCI WorldTeams, with the exception of the teams that the organizers invite. Traditionally, the bulk of the race is held in July. While the route changes each year, the format of the race stays the same and includes time trials, passage through ...

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 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 (UCI). As well as the UCI's annual UCI Road World Champio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankset
The crankset (in the US) or chainset (in the UK) is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called ''chainrings'' or ''chainwheels'' attached to the '' cranks'', ''arms'', or ''crankarms'' to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain. Parts Cranks The two ''cranks'', one on each side and usually mounted 180° apart, connect the bottom bracket axle to the pedals. Lengths Bicycle cranks can vary in length to accommodate different sized riders and different types of cycling. Crank length is measured from the center of the pedal spindle to the center of the bottom bracket spindle or axle. The larger bicycle component manufacturers typically offe ...

Grand Tour (cycling)
In road bicycle racing, a Grand Tour is one of the three major European professional cycling stage (bicycle race), stage races: Giro d'Italia, Tour de France, and Vuelta a España. Collectively they are termed the ''Grand Tours'', and all three races are similar in format, being three-week races with daily stages. They have a special status in the Union Cycliste Internationale, UCI regulations: more points for the UCI World Tour are distributed in Grand Tours than in other races, and they are the only stage races allowed to last longer than 14 days, and these differ from major stage races more than one week in duration. All three races have a substantial history, with the Tour de France first held in 1903, Giro d'Italia first held in 1909 and the Vuelta a España first held in 1935. The Giro is generally run in May, the Tour in July, and the Vuelta in late August and September. The Vuelta was originally held in the spring, usually late April, with a few editions held in June in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flanders
Flanders ( or ; ) is the Dutch language, Dutch-speaking northern portion of Belgium and one of the communities, regions and language areas of Belgium. However, there are several overlapping definitions, including ones related to culture, language, politics, and history, and sometimes involving neighbouring countries. The demonym associated with Flanders is Flemings, Fleming, while the corresponding adjective is Flemish people, Flemish, which can also refer to the collective of Dutch dialects spoken in that area, or more generally the Belgian variant of Standard Dutch. Most Flemings live within the Flemish Region, which is a federal state within Belgium with its own elected government. However, like Belgium itself, the official capital of Flanders is the City of Brussels, which lies within the Brussels, Brussels-Capital Region, not the Flemish Region, and the majority of residents there are French speaking. The powers of the Flemish Government in Brussels are limited mainly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Points Race
A points race is a mass start track cycling event involving large numbers of riders simultaneously on track. It was an Olympic event for men from 1984 to 2008 and for women from 1996 to 2008. Since 2012, the points race has been one of the omnium events in the Olympics. Description The races are run over 40 km for men and 25 km for women in UCI championships. A sprint is held every ten laps, with 5, 3, 2, and 1 point(s) being awarded to the top four finishers in each sprint. The winner of the race is the one to have the most points at the end of the race. In addition to the sprints, any riders managing to lap the main field are awarded an extra 20 points. This is therefore a popular way of gaining the points required to win the race and leads to many such attempts to gain a lap during the race. Different tactics can be employed to win the race. Some riders may sit back in the main bunch conserving energy, only attacking for the sprints to gain points. Other riders may ...

Racing Bicycle
A racing bicycle, also known as a road bike, is a bicycle designed for competitive road cycling, a sport governed by and according to the rules of the Union Cycliste Internationale (UCI). Racing bicycles are designed for maximum performance while remaining legal under the UCI rules. They are designed to minimise aerodynamic drag, rolling resistance, and weight, and balance the desire for stiffness for pedaling effiency with the need for some flexibility for comfort. Racing bicycles sacrifice comfort for speed compared to non-racing bicycles. The drop handlebars are positioned lower than the saddle to put the rider in a more aerodynamic posture. The front and back wheels are close together so the bicycle has quick handling, which is preferred by experienced racing cyclists. The derailleur gear ratios are closely spaced so that the rider can pedal at their optimum cadence. However, racing bicycles must retain the ability to maneuver safely within a tightly-packed peloton, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheelbase
In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the steering (front) axle and the centerpoint of the driving axle group. In the case of a tri-axle truck, the wheelbase would be the distance between the steering axle and a point midway between the two rear axles. Vehicles The wheelbase of a vehicle equals the distance between its front and rear wheels. At equilibrium, the total torque of the forces acting on a vehicle is zero. Therefore, the wheelbase is related to the force on each pair of tires by the following formula: :F_f = mg :F_r = mg where F_f is the force on the front tires, F_r is the force on the rear tires, L is the wheelbase, d_r is the distance from the center of mass (CM) to the rear wheels, d_f is the distance from the center of mass to the front wheels (d_f + d_r = L), m is the mass ...

Bicycle And Motorcycle Geometry
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail. These parameters have a major influence on how a Bicycle and motorcycle dynamics, bike handles. Wheelbase The wheelbase is the ''horizontal'' distance between the centers (or the ground contact points) of the front and rear wheels. Wheelbase is a function of rear frame length, steering axis angle, and fork offset. It is similar to the term wheelbase used for automobiles and trains. Wheelbase has a major influence on the Bicycle and motorcycle dynamics#Stability, longitudinal stability of a bike, along with the height of the center of mass of the combined bike and rider. Short bikes are much more suitable for performing wheelies and stoppies. Steering axis angle The steering axis angle is called ''caster angle'' when measured from vertical axis or ''head angle'' w ...
