Von Hippel y la bici de montaña en su libro Free Innovation
Aunque no es ninguna sorpresa porque el sector de la bici de montaña siempre ha sido mencionado como pionero en cuanto a innovación de usuario, es gratificante encontrar referencias nada más comenzar a leer este último libro de von Hippel. Así en la página 10 se dice:
For example, a specialized mountain bike is of little value to a biker who has not learned specialized mountain biking techniques. Producers find it viable to produce and sell the specialized mountain bikes as commercial products, but largely rely on expert bikers innovating within the free paradigm to create and diffuse riding techniques as a free complement. That is, adopters generally learn new mountain biking techniques by a combination of self-practice and informal instruction freely given by more expert peers.
