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, wins the prime. Success in road criteriums requires a mix of good technical skills — in ...

Tour De France
The Tour de France () is an annual men's multiple-stage bicycle race primarily held in France, while also occasionally passing through nearby countries. Like the other Grand Tours (the Giro d'Italia and the Vuelta a España), it consists of 21 stages, each a day long, over the course of 23 days, coinciding with the Bastille Day holiday. It is the oldest of the Grand Tours and generally considered the most prestigious. The race was first organized in 1903 to increase sales for the newspaper '' L'Auto'' and is currently run by the Amaury Sport Organisation. The race has been held annually since its first edition in 1903 except when it was stopped for the two World Wars. As the Tour gained prominence and popularity, the race was lengthened and its reach began to extend around the globe. Participation expanded from a primarily French field as more riders from all over the world began to participate in the race each year. The Tour is a UCI World Tour event, which means that th ...

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).

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 offer cr ...

Grand Tour (cycling)
In road bicycle racing, a Grand Tour is one of the three major European professional cycling 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 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. 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 the 1940s. In 1995, however, the race moved to September to avoid direct competition with the Giro d'Italia. The Tour de Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flanders
Flanders (, ; Dutch: ''Vlaanderen'' ) is the Flemish-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 Fleming, while the corresponding adjective is Flemish. The official capital of Flanders is the City of Brussels, although the Brussels-Capital Region that includes it has an independent regional government. The powers of the government of Flanders consist, among others, of economic affairs in the Flemish Region and the community aspects of Flanders life in Brussels, such as Flemish culture and education. Geographically, Flanders is mainly flat, and has a small section of coast on the North Sea. It borders the French department of Nord to the south-west near the coast, the Dutch provinces of Zeeland, North Brabant an ...

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 between 1984–2008 and for women 1996–2008. Starting in 2012, the points race is 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 attem ...

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 in order 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 pe ...

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 ...

Rake (angle)
A rake is an angle of slope measured from horizontal, or in some contexts from a vertical line 90° perpendicular to horizontal. A 60° rake would mean that the line is pointing 60° up from horizontal, either forwards or backwards relative to the object. Usage Though the term may be used in a general manner, it is commonly applied in several specific contexts. The rake of a ship's prow is the angle at which the prow rises from the water (the rake below water being called the bow rake). A motorcycle or bicycle fork rake is the angle at which the forks are angled down towards the ground. See also caster angle, which is the angular displacement of the steering axis from the vertical axis of a steered wheel. In machining and sawing the rake angle Rake angle is a parameter used in various cutting and machining processes, describing the angle of the cutting face relative to the work. There are three types of rake angles: ''positive'', ''zero'' or ''neutral'', and ''negative'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 bike handles. Wheelbase 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 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 when measured from horizontal axis. The steering axis is the axis about which the steeri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
