| 释义 |
and is used as a "marketing term" by some manufacturers for their 27.5", the 650B has traditionally been a designation for a 26 inch diameter (ISO ~ 40-584 demi-ballon tire) using the same ISO 584 mm rim[9] used by French tandems, Porteurs and touring bicycles.[4][7][10] The 27.5 inch are seen as a compromise between the two existing standards of the original 26 inch (ISO 559 mm rim) and recently emerged 29 inch mountain bikes. They were pioneered by Kirk Pacenti in 2007,[1][11] and as of 2013, at least 10 companies are launching models with 27.5 inch wheels,[4] and parts manufacturers are following suit.[2][5] Nino Schurter won the World Cup event at Pietermaritzburg, South Africa,[6] and placed second in the Olympics in 2012 on 27.5 inch wheels.[3]See also{{Portal|Bicycles}}
