Dolomites
The Dolomites ( it, Dolomiti ; Ladin: ''Dolomites''; german: Dolomiten ; vec, Dołomiti : fur, Dolomitis), also known as the Dolomite Mountains, Dolomite Alps or Dolomitic Alps, are a mountain range located in northeastern Italy. They form part of the Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley ( Pieve di Cadore) in the east. The northern and southern borders are defined by the Puster Valley and the Sugana Valley (Italian: ''Valsugana''). The Dolomites are located in the regions of Veneto, Trentino-Alto Adige/Südtirol and Friuli Venezia Giulia, covering an area shared between the provinces of Belluno, Vicenza, Verona, Trentino, South Tyrol, Udine and Pordenone. Other mountain groups of similar geological structure are spread along the River Piave to the east – ''Dolomiti d'Oltrepiave''; and far away over the Adige River to the west – ''Dolomiti di Brenta'' (Western Dolomites). A smaller group is called ''Piccole Dolo ...

Aune
An ell (from Proto-Germanic *''alinō'', cognate with Latin ''ulna'') is a northwestern European unit of measurement, originally understood as a cubit (the combined length of the forearm and extended hand). The word literally means "arm", and survives in the form of the modern English word "elbow" (arm-bend). Later usage through the 19th century refers to several longer units, some of which are thought to derive from a "double ell". An ell-wand or ellwand was a rod of length one ell used for official measurement. Edward I of England required that every town have one. In Scotland, the Belt of Orion was called "the King's Ellwand". An iron ellwand is preserved in the entrance to Stånga Church on the Swedish island of Gotland, indicating the role that rural churches had in disseminating uniform measures. Several national forms existed, with different lengths, including the Scottish ell , the Flemish ell l, the French ell une,Brayshaw, Tom S., ed. ''Brayshaw's Mathemati ...

Tullio Campagnolo
Gentullio Campagnolo (26 August 1901 – 3 February 1983) was an Italian racing cyclist and inventor who patented the quick release skewer, as well as founder of the bicycle component company Campagnolo. Many professional cyclists have used Campagnolo components, including Fausto Coppi, Gino Bartali, Eddy Merckx (Merckx was a close friend of Campagnolo and became an iconic symbol of the company), Bernard Hinault, Greg LeMond, Miguel Indurain and Philippe Gilbert. Background Campagnolo was born in Vicenza, Italy in 1901 to a middle-class family, and began his tinkering of inventions at his father's hardware store. In 1922 Campagnolo began his amateur cycling career. He was an avid cyclist riding many races, such as the Giro di Lombardia, Milan–San Remo, and several Olympic heats. While racing through the Italian Dolomites on 11 November 1927, in freezing weather and snow, Campagnolo lost the race due to a wingnut he could not remove to change gears. The title that was lost a ...

Quick Release Skewer
A quick release skewer is a mechanism for attaching a wheel to a bicycle. It consists of a rod threaded on one end and with a lever operated cam assembly on the other. The rod is inserted into the hollow axle of the wheel, a special nut is threaded on, and the lever is closed to tighten the cam and secure the wheel to the fork. Wheels equipped with quick release mechanisms can be removed from the bicycle frame and replaced without using tools by opening and closing the cam lever, thus more quickly than wheels with solid axles and nuts. On the negative side, a quick-release hub renders a wheel more vulnerable to theft and care must be taken to ensure that the mechanism is properly tightened. Similar quick-release mechanisms are also used to operate seatpost clamps, and the collapsing stem of folding bicycles and kick scooters. History The mechanism was invented in 1927 by Tullio Campagnolo, an Italian bicycle racer. He was frustrated when he attempted to change gears durin ...
