Sheldon Brown: Unterschied zwischen den Versionen

Sheldon Brown war bei [[Harris Cyclery]], einem [[Fahrradgeschäft]] in West Newton (Massachusetts, [[USA]]) als "Parts Manager, Webmaster and general Tech Guru" angestellt. Er engagierte sich enthusiastisch für viele alte und ungewöhnliche Arten von Fahrrädern und Fahrradfahren insbesondere [[Raleigh Bicycle Company|Raleigh]] und ihre Englische [[3-Gang Fahrrad|3-Gang Fahrräder]], die [[Sturmey-Archer]] Gengschaltung im generellen, [[Tandem|Tandems]] und im speziellen [[Starrgangfahrrad|Fixies]]. Er reparierte Kameras und war versierter Amateurfotograf. Seine Website ist mit seinen Werken reichhaltig illustriert.

Sheldon wrote a well-regarded guide to [[wheelbuilding]], available on his website. He also established the [[Mirror (computing)|mirror sites]] of the technical work of Damon Rinard and others.  

With the assistance of Galen Evans and Osman Isvan, Brown developed a new method for determining and comparing bicycle gear ratios. His method, which, for any combination of front chainring, rear cog, wheels size and crank length, results in a pure ratio that Brown terms the "gain ratio."  This method purports to be the only formula that takes into account crank length in addition to the more commonly considered chainring, cog and wheel size factors. <ref>{{cite web |url=http://www.sheldonbrown.com/gain.html |title=Gain Ratios |accessdate=2008-02-08 |last=Brown |first=Sheldon |publisher=Sheldon Brown}}</ref>

On some groups, links to his site in response to technical questions were flagged with the abbreviation '''AASHTA''' (As Always, Sheldon Has The Answer).

 

In 2004, Sheldon was recognized for his contribution to cycling by the [[United Kingdom|UK]]'s [[Cyclists' Touring Club]] (CTC). Sheldon Brown wrote the "Mechanical Advantage" column for ''Adventure Cyclist'' magazine. His site is referenced in the technical library of the CTC.<ref>{{Citation
