Pedaling
The pedal is the part of a bicycle that the rider pushes with their foot to propel the vehicle. It provides the connection between the cyclist's foot or shoe and the crank allowing the leg to turn the bottom bracket spindle and propel the bicycle's wheels. A pedal usually consists of a spindle that threads into the end of the crank, and a body on which the foot rest is attached, that is free to rotate on bearings with respect to the spindle. Pedals were initially attached to cranks connecting directly to the driven (usually front) wheel. The safety bicycle, as it is known today, came into being when the pedals were attached to a crank driving a sprocket that transmitted power to the driven wheel by means of a roller chain. Types Just as bicycles come in many varieties, there are different types of pedals to support different types of cycling. Flat and platform Traditionally, platform pedals were pedals with a relatively large flat area for the foot to rest on, in contra ...

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 ...

Bicycle Pedal, Quill Type, Early 1980s, Campagnolo SL Road
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Biking
Mountain biking is a sport of riding bicycles off-road, often over rough terrain, usually using specially designed mountain bikes. Mountain bikes share similarities with other bikes but incorporate features designed to enhance durability and performance in rough terrain, such as air or coil-sprung shocks used as suspension, larger and wider wheels and tires, stronger frame materials, and mechanically or hydraulically actuated disc brakes. Mountain biking can generally be broken down into five distinct categories: cross country, trail riding, all mountain (also referred to as "Enduro"), downhill, and freeride. This sport requires endurance, core strength and balance, bike handling skills, and self-reliance. Advanced riders pursue both steep technical descents and high incline climbs. In the case of freeride, downhill, and dirt jumping, aerial maneuvers are performed off both natural features and specially constructed jumps and ramps. Mountain bikers ride on off-road trails ...

Look (company)
Look is a French sports equipment manufacturing company based in Nevers that has led the innovation of alpine skiing quick-release binding systems. The company later moved into cycling with innovations in clipless pedals and carbon fiber frames. The Look logo was inspired by Piet Mondrian paintings. History In 1948, engineer and inventor Jean Beyl, who owned a rubber manufacturing company, broke his leg skiing whilst wearing a rigid ski binding, which then brought him into the fledgling safety binding business. In 1950, Beyl invented the Look Nevada dual-pivot ski binding system. The following year the Look company was founded, named after the American magazine Look. The 1962 Look Nevada II single-pivot ski binding design was the main influence for the company's bindings over the next 40 years. Following Beyl's early designs of a clipless bicycle pedal, in 1983, Look was bought by French businessman Bernard Tapie, who created the professional cycling team La Vie Claire th ...

Cinelli
Cinelli () is an Italian bicycle manufacturing company based in Milan, producing mostly road bicycles and components; production is estimated to consist of 80 per cent components and 20 per cent bicycles. History Cinelli was founded in 1948 by Cino Cinelli (born Montespertoli, 9 February 1916, died 20 April 2001), a former professional road racer and president of the Italian Cyclists' Association. He was a professional racer from 1937 to 1944, winning Milan–San Remo in 1943, the Giro di Lombardia in 1938, and the Tour of the Apennines in 1937. He started a company under his name in 1948. Cinelli was the seventh of 10 children, the son of a small landowner near Florence. He became interested in bicycle technology after mechanical failures in races. Failure to interest manufacturers with his ideas in 1946 led him to start his own company. His brother Giotto was making steel stems and bars in Florence and Cinelli moved the business to Milan, centre of the Italian cycling ...

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial researc ...

Cycling Shoe
Cycling shoes are shoes purpose-built for cycling. There are a variety of designs depending on the type and intensity of the cycling for which they are intended. Key features include rigidity, for more-efficient transfer of power from the cyclist to the pedals, weight, a method of attaching the shoe firmly to the pedal and adaptability for use on and off the bicycle. Most high-performance cycling shoes can be adjusted while in use, via a quick-adjusting system that has largely replaced laces. Pedal systems Modern cycling shoes are designed to work with clipless pedal systems. Such systems temporarily connect the shoe to the pedal like a ski binding system for maximal efficiency of power-transfer using a cleat on the bottom of each shoe and a matched fitting on the pedal. Several manufacturers produce these systems; consequently, modern shoes usually have threaded holes in the sole in various arrangements to attach cleats from different manufacturers. Broadly there are two styles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
