The British brand Sturmey-Archer was founded in Nottingham in 1902, following the meeting of Frank Bowden with Professor Henry Sturmey and engineer James Archer.
Both had designed a 3-speed hub for bicycles, Bowden, inventor of the brake cable, used it for gear control.

In 2002, Sturmey Archer was acquired by the Taiwanese brand SunRace, which now handles all of its manufacturing.
