The fixed gear bicycle is the simplest of human powered machines, and legions of riders have discovered the joy of the "fixie." To those in the know, 42 x 12 is a gear ratio, and a demanding one at that, but this isn't a book about equipment, rather an attempt to get under the skin of riders risking life and limb in pursuit of their passion. 42 x12 - The Cult of Fixed examines the global repercussions of fixed-gear and single speed bicycle culture. Through contemporary observation and the collaboration of those on the inside from Taiwan to New York, London to Tokyo, 42 x12 gives a unique insight into what's going on at ground level. Features within 42 x 12 include; The Tweed Run, as distinguished gents bring style and sophistication to the streets of London; messenger and alley cat racing, requiring the need for more than just speed in an urban environment; indoor and keirin racing, eyeballs out at 150 Revolutions per minute.
