Wheel Truing Stand
A wheel truing stand is a specialized tool for "truing" (straightening) bicycle wheels. Individual models differ slightly, but all consist of an axle stand on which the wheel can rotate and calipers, to measure slight deviations of the wheel's rim from ideal alignment. Proper wheel alignment includes lateral, radial and dish/centering trues which keep the wheel straight and strong. The stand is used in conjunction with an appropriately sized spoke wrench to loosen or tighten the spokes that connect the wheel's hub to the rim. Types of Wheel Trues All types of wheel trues are necessary when keeping a wheel strong. Proper spoke tensions will help a wheel snap back to true if under specific load. *Lateral: Measures the rim horizontally in order to keep the rim straight. * Radial: Measures the rims diameter to keep the wheel circular (also known as eliminating hops). * Dish/Centering: Centers the rim above the hub; dish tool is used to measure centering. All wheels are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U Wash Bicycle Shop 02A
U or u, is the twenty-first and sixth-to-last Letter (alphabet), letter and fifth vowel letter of the Latin alphabet, used in the English alphabet, modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is English alphabet#Letter names, ''u'' (pronounced ), plural English alphabet#Letter names, ''ues''. History U derives from the Semitic Waw (letter), waw, as does F, and later, Y, W, and V. Its oldest ancestor goes to Egyptian hieroglyphs, Egyptian hieroglyphics, and is probably from a hieroglyph of a mace or fowl, representing the sound [Voiced labiodental fricative, v] or the sound [Voiced labial–velar approximant, w]. This was borrowed to Phoenician, where it represented the sound [w], and seldom the vowel [Close back rounded vowel, u]. In Greek language, Greek, two letters were adapted from the Phoenician waw. The letter was adapted, but split in two, with the Digamma, first one of the same name (Ϝ) being ada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wiki Single Arm Model
A wiki ( ) is an online hypertext publication collaboratively edited and managed by its own audience, using a web browser. A typical wiki contains multiple pages for the subjects or scope of the project, and could be either open to the public or limited to use within an organization for maintaining its internal knowledge base. Wikis are enabled by wiki software, otherwise known as wiki engines. A wiki engine, being a form of a content management system, differs from other web-based systems such as blog software, in that the content is created without any defined owner or leader, and wikis have little inherent structure, allowing structure to emerge according to the needs of the users. Wiki engines usually allow content to be written using a simplified markup language and sometimes edited with the help of a rich-text editor. There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems. Some wiki engines are open ...

Tool
A tool is an object that can extend an individual's ability to modify features of the surrounding environment or help them accomplish a particular task. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early human tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts. The development of metalworking made additional types of tools possible. Harnessing energy sources, such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an inflection point in the use of tools. The introduction of widespread automation in the 19th and 20th centuries allowed tools to operate with minimal human supervision, further increasing the productivity of ...

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. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calipers
A caliper (British spelling also calliper, or in plurale tantum sense a pair of calipers) is a device used to measure the dimensions of an object. Many types of calipers permit reading out a measurement on a ruled scale, a dial, or a digital display. Some calipers can be as simple as a compass with inward or outward-facing points, but no scale. The tips of the caliper are adjusted to fit across the points to be measured and the dimension read by measuring between the tips with another measuring tool, such as a ruler. It is used in many fields such as mechanical engineering, metalworking, forestry, woodworking, science and medicine. Plural vs. singular A single tool might be referred to as a "caliper" or as "calipers", like a pair of scissors or glasses (a "plural only" or ''plurale tantum'' form). In colloquial usage, the phrase "pair of verniers" or just " vernier" might refer to a vernier caliper. Colloquially these phrases can also refer to dial calipers, although they in ...

Spoke Wrench
A spoke wrench or spoke key is a small wrench or tool used to adjust the tension in the spokes of a tension-spoked wheel. A spoke wrench is sometimes called a nipple wrench, as it is the spoke nipple – not the spoke – that is turned in the process of changing the tension of a spoke. Overview Spoke nipples are typically T-shaped in cross section, with an internal thread running part of the way through the hole that runs along the spoke nipple's principal axis. A spoke nipple rests in a hole drilled radially through the wheel's rim, and the nipple is threaded onto the external thread of a spoke. The spoke itself is fixed, at its other end, through a hole in the hub. The spoke and nipple are functionally equivalent to a bolt and a nut. However, unlike a typical nut-and-bolt pair, a spoke and nipple do not join two parts (the rim and the hub) so much as bridge them, under tension. The area of the nipple around which the spoke wrench, or key, is fitted is generally square in cross-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spoke
A spoke is one of some number of rods radiating from the center of a wheel (the hub where the axle connects), connecting the hub with the round traction surface. The term originally referred to portions of a log that had been riven (split lengthwise) into four or six sections. The radial members of a wagon wheel were made by carving a spoke (from a log) into their finished shape. A spokeshave is a tool originally developed for this purpose. Eventually, the term spoke was more commonly applied to the finished product of the wheelwright's work, than to the materials they used. History The spoked wheel was invented to allow the construction of lighter and swifter vehicles. Earliest physical evidence for spoked wheels were found in Sintashta culture, dating to 2000 BC. Soon after this, horse cultures of the Caucasus region used horse-drawn spoked-wheel war chariots for the greater part of three centuries. They moved deep into the Greek peninsula where they joined with the exis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spoke Nipple
A spoke nipple holds a bicycle wheel's rim to each spoke. The spoke nipple is a headed cylinder with threading on the inside through part of its length (there is an unthreaded lead-in nearest the "flats"). Traditionally, the nipples fit in holes in the rim, so that the head of the nipple is on the outermost part of the rim, while the other end of the nipple points inwards towards the hub. Many different types of nipples are now available, including internal nipples that sit entirely within the rim and can only be adjusted by removing the tire, as well as externally threaded nipples that thread into the rim (such as those used by Mavic Ksyriums). The threading grasps the spoke, so turning it increases or decreases tension in the spoke and influences the position of the hub relative to the rim. Thread pitch can vary with thread size, but is 0.454mm for common spoke thicknesses, which use thread types Fg 2, Fg 2.3 or Fg 2.6. Since spoke threading and nipple threading must match, ...

Park Tool
Park Tool Company is an American designer, manufacturer and marketer of bicycle tools and equipment for both professional and home bicycle mechanics. It manufactures about 4000 products that range from wheel truing stands to hex wrenches. History In 1963, Howard C. Hawkins and Art Engstrom were the owners of Park Schwinn, a bicycle shop in the Hazel Park area of Saint Paul, Minnesota. They noticed that there were no tools available to repair the increasingly complex bicycles of the 1960s, so they began creating their own tools. The first was a stand that held the bike off the ground allowing convenient access to any part of the bike. Other area bike shops and Schwinn Bicycle Company liked the stands and requested a production model. Soon after, the company expanded to include wheel truing stands, then expanded further into consumer wrenches and gauges. By the early 1980s, Hawkins and Engstrom were a perennial top ten Schwinn dealer with three stores but sold their bicycle shops ...
