The boom in sales of mountain bikes resulted in rapid expansion. Twenty-five years later, it had become clear that further growth would only result from higher level components and so commenced the process of taking the product range up-market. That procedure accelerated after internal hub gear supplier sturmey-archer was purchased in 2000. Sturmey-archer was first established in England in 1902 when they invented the 3-speed internal gear hub.
