Triathlon Equipment
Due to the nature of triathlons as a race consisting of multiple sports many pieces of technical equipment have been borrowed from other sports, or developed specifically in an effort to race faster and improve a competitors safety. Trisuits A trisuit is a single Skin-tight garment, skin tight item of clothing designed specifically for triathlon athletes to provide comfort and remove the necessity to change clothing while switching from swimming to cycling to running. Normally a trisuit is a single item of clothing; however, two-piece versions exist with separate shorts and top. These are mainly chosen for longer races where comfort is more important. All trisuits have a Cycling pad, cycling chamois built in for comfort on the bike leg of the competition. However, these are thinner than traditional shorts for cycling to allow the wearer to run without additional friction. Traditionally, trisuits have no sleeves to allow for greater shoulder mobility for swimming, but trisuits w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triathlon
A triathlon is an endurance multisport race consisting of Swimming (sport), swimming, Cycle sport, cycling, and running over various distances. Triathletes compete for fastest overall completion time, racing each segment sequentially with the time transitioning between the disciplines included. The word is of Greek language, Greek origin, from (), 'three', and (), 'competition'. The sport originated in the late 1970s in Southern California as sports clubs and individuals developed the sport. This history has meant that #Nonstandard variations, variations of the sport were created and still exist. It also led to other three-stage races using the name triathlon despite not being continuous or not consisting of swim, bike, and run elements. Triathletes train to achieve endurance, strength, and speed. The sport requires focused persistent and Sports periodization, periodised training for each of the three disciplines, as well as combination workouts and general strength conditio ...

International Triathlon Union
World Triathlon, previously known as the International Triathlon Union (ITU), is the international governing body for the multi-sport disciplines of triathlon, duathlon, aquathlon and other nonstandard variations. It is recognised as the international federation for the sport of triathlon and its derivatives by the International Olympic Committee, and it organises Olympic triathlon events on behalf of the IOC. In addition to regulating and setting the rules of the sport, World Triathlon organises the top level international race series the World Triathlon Championship Series and the ITU Triathlon World Cup. Starting in 2024, World Triathlon also sanctions and recognises a World Championship Tour of Long-Distance Triathlon organised by the Professional Triathletes Organisation. World Triathlon does not have an official relationship with the other three major commercial triathlon circuits, Ironman Triathlon, XTERRA Triathlon or Super League Triathlon. Additionally, World Tri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Softride
Softride was a manufacturer of bicycles located in Bellingham, Washington. They specialized in bicycles for triathletes. The bicycle frames were distinctive for their lack of seat tubes and seat stays. The idea was to reduce aerodynamic drag and improve ride comfort. The company no longer manufactures bicycles, and focuses on bicycle carriers instead. The design was developed by James Allsop and David Calopp, and became the most successful of the beam suspension systems. It was intended as a retrofit for traditional diamond frame bicycles, at first, but there were concerns about causing frame damage. Notable Softride users include Greg Welch and Jürgen Zäck. In a survey of bicycles ridden at the 1996 Ironman World Championship in Kona, Hawaii, there were 126 Softrides, out of 857 total bicycles, representing 14.7%. That was an increase from the 11.9% of 798 bicycles in 1995. Softride Suspension System The Softride Suspension System was launched at the Interbike 1989 bi ...

Zipp 2001
Zipp 2001 and 3001 were a line of bicycle frames, currently discontinued, made by the Zipp company. Although they have been out of production since 1997, they still have a cult following within triathlon, where they remain race-legal . The Zipp 2001 is part of a significant advance in mid-1990s bicycle design, where new materials such as aluminum and carbon fiber allowed for new, less orthodox frame designs. Other examples include Hotta, Softride, Trek's Y-foil, and the Cheetah Cat. Timeline The frame that was to become the 2001 was first shown in prototype form in 1990, finalized in 1991, and entered production in 1992. The Zipp 3001 (which was a 2001 with additional boron strips stiffening the carbon fiber) was released in 1997. In 1998, the Union Cycliste Internationale, UCI announced that all non-double triangle frames would be illegal for road racing starting in January 2000. This led Zipp to discontinue production at the end of 1997. The existing component inventory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphite-reinforced Plastic
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (English in the Commonwealth of Nations, Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermosetting polymer, thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester resin, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Wheel
A bicycle wheel is a wheel, most commonly a wire wheel, designed for a bicycle. A pair is often called a wheelset, especially in the context of ready built "off the shelf" performance-oriented wheels. Bicycle wheels are typically designed to fit into the bicycle frame, frame and bicycle fork, fork via Dropout (bicycle part), dropouts, and hold bicycle tires. Invention The first wheel to use the tension in wire wheel, metal spokes was invented by George Cayley, Sir George Cayley to achieve lightness in his 1853 glider. Construction The first bicycle wheels followed the traditions of carriage building: a wooden hub, a fixed steel axle (the bearings were located in the fork ends), wooden spokes and a shrink fitted iron tire. A typical modern wheel has a metal hub, wire tension spokes and a metal or carbon fiber rim which holds a pneumatic rubber tire. Hub A hub is the center part of a bicycle wheel. It consists of an axle, bearing (mechanical), bearings and a hub shell. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Handlebar
A bicycle handlebar is the steering control for bicycles. It is the equivalent of a tiller for vehicles and vessels, as it is most often directly mechanically linked to a pivoting front wheel via a Stem (bike), stem which in turn attaches it to the Bicycle fork, fork. Besides steering, handlebars also often support a portion of the rider's weight, depending on their riding position, and provide a convenient mounting place for Bicycle brake, brake levers, Shifter (bicycle part), shift levers, cyclocomputers, Bicycle bell, bells, etc. History The dandy horse, or draisienne, invented by Karl Drais and the first vehicle with two wheels arranged in tandem, was controlled by a bar connected to the front steering mechanism and held by the riders' two hands. The first handlebars were solid bars of steel or wood, depending on the manufacturer. Curved, moustache-shaped, drop handlebars became popular in the 1920s. Whatton bars were developed in attempt to improve the safety of penny-farth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bicycle Frame
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the ''diamond frame''. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and fork of a bicycle and sometimes includes the headset and seat post. Frame builders will often produce the frame and fork together as a paired set. Variations Besides the ubiquitous diamond frame, many different frame types have been developed for the bicycle, several of which are still in common use today. Diamond In the diamond frame, the main "triangle" is not actually a triangle because it consists of four tubes: the head tube, top tube, down tube and seat tube. The rear triangle consists of the seat tube joined by p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drafting (racing)
Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure and can even slightly reduce the energy expenditure of the lead vehicle. Drafting in sport Drafting is used to reduce wind resistance and is seen most commonly in bicycle racing, motorcycle racing, car racing, and speedskating, though drafting is occasionally used even in cross-country skiing, downhill skateboarding, and running. Some forms of triathlon allow drafting. Drafting occurs in swimming as well: both in open-water races (occurring in natural bodies of water) and in traditional races in competition pools. In a competition pool a swimmer may hug the lane line that separates them from the swimmer they are abaft of thereby taki ...

Aerodynamics
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...

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] |
