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 pel ...

International Human Powered Vehicle Association
The International Human Powered Vehicle Association (IHPVA) is a US-based organization dedicated to promoting the design and development of human powered vehicles (HPVs) and the keeping of speed and distance records for these vehicles and bikes. History The IHPVA was founded in in the USA and was for many years an association of individual members with the publications Human Power and HPV News. In , the IHPVA was reorganised into an international association with national organisations as members and an American association which adopted the name Human Powered Vehicle Association HPVA. Due to conflicts regarding record keeping and copyrights, the HPVA left the IHPVA in 2004. In , the HPVA renamed itself to IHPVA while the IHPVA of this time decided to keep its name, resulting in a brief period with two organisations of the same name. In a hostile takeover, the American IHPVA also seized control of the domain name ihpva.org away from the international IHPVA. This tried to regai ...

Carbon Fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (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 thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other a ...

Titanium
Titanium is a chemical element with the Symbol (chemistry), symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Kingdom of Great Britain, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titan (mythology), Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll process, Kroll and Hunter process, Hunter processes. The most common compound, titanium dioxide, is a popular photocatalysis, photocatalyst and is used in the manufacture of white pigments ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Giant Bicycles
Giant Manufacturing Co. Ltd. (commonly known as Giant) is a Taiwanese bicycle manufacturer, recognized as the world's largest bicycle designer and manufacturer. Giant has manufacturing facilities in Taiwan, the Netherlands, China, and Hungary. History Giant was established in 1972 in Dajia, Taichung County in Taiwan (now part of Taichung City), by King Liu and several friends. A major breakthrough came in 1977 when Giant's chief executive, Tony Lo, negotiated a deal with Schwinn to begin manufacturing bikes as an OEM, manufacturing bicycles to be sold exclusively under other brand names as a private label. As bike sales increased in the U.S., and after workers at the Schwinn plant in Chicago went on strike in 1980, Giant became a key supplier, making more than two-thirds of Schwinn bikes by the mid-1980s, representing 75% of Giant's sales. When Schwinn decided to find a new source and in 1987 signed a contract with the China Bicycle Company to produce bikes in Shenzhen, Gian ...

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] |
Gravel Bicycle
A gravel bicycle is a type of bicycle intended for gravel cycling, including gravel racing. They are also sometimes known as "adventure bicycles", particularly ones intended for harsher off-road terrain. While bicycles have been used for riding on such roads since bicycles were invented, the "modern" gravel bicycle, as a category, evolved in the 2000s, adopting technology from road bicycles, cyclocross bicycles and mountain bikes. They also share many characteristics of touring bicycles, such as relaxed geometry, wide tires and wide-range gearing. Design characteristics Gravel bikes have been constructed out of a wide variety of frame materials, including aluminium, carbon fibre, titanium and steel. Most use carbon fibre forks. Gravel bicycles generally use drop bars, similar to racing and cyclocross bicycles, unlike mountain bikes and hybrid bicycles. Many gravel bikes are fitted with wider bars than would be typical for a road or cyclocross bike, and a few have been f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclo-cross Bicycle
A cyclo-cross bike or cyclo-cross bicycle (abbreviated CX Bike or CXB) is a bicycle specifically designed for the rigors of a cyclo-cross race. Cyclo-cross bicycles roughly resemble the racing bicycles used in road racing. The major differences between the two are the frame geometry, and the wider clearances that cyclo-cross bikes have for their larger tires and mud and other debris that they accumulate. Cyclists have been competing in races on road-going bicycles since the 19th century. Cyclo-cross emerged as a sport in its own right in France in 1902. Cyclo-cross bicycles are similar to other bicycles, but the frame geometry is closer to a mountain bike than a road racing bicycle. The top tube is often longer and closer to horizontal, and the handlebars are higher, again akin to mountain bikes. The emphasis on bicycle handling skills differentiates cyclo-cross from road racing. Cyclo-cross courses are held on a variety of terrain, including grass, mud, sand and paved surfac ...

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. World Triathlon hosts the top level international race series the World Triathlon Championship Series and the ITU Triathlon World Cup. World Triathlon also has a long-distance race circuit with official world championships. Additionally, World Triathlon sanctions and organizes official Aquathlon (run-swim-run), Duathlon (run-bike-run) and Winter triathlon championships. World Triathlon is headquartered in Lausanne, Switzerland History Versions of swim bike run multi-sports existed in the 1920s, but it wasn't until the term triathlon was coined in 1974 in San Diego that triathlon exploded in popularity. This rapid development drew the attention of the International Olympic Committee (IOC), which initiated a discussion in 1988 to include it in the Olympic Games progra ...

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 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 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 with tight-fitting sleeves have b ...

Triathlon
A triathlon is an endurance multisport race consisting of swimming, 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 origin, from τρεῖς or ''treis'' (three) and ἆθλος or ''athlos'' (competition). The sport originated in the late 1970s in Southern California as sports clubs and individuals developed the sport. This history has meant that 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 periodised training for each of the three disciplines, as well as combination workouts and general strength conditioning.
