27.5 Mountain bike

Merida Big Seven mountain bike with Schwalbe Racing Ralph 27.5" tires

27.5 mountain bikes, also called tweeners,[1] are mountain bikes which use a wheel that is approximately 27.5 inches in diameter with the mountain bike tire installed.[2][3][4][5][6] The wheel size is also known as ISO 584 mm and 650B.[7][8] Some manufacturers are also marketing them as 650b.[4] They are seen as a compromise between the two existing standards of the original 26 inch and recently emerged 29 inch mountain bikes. They were pioneered by Kirk Pacenti in 2007,[1][9] 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]
