Boas,
Durante mais uma sessão de pesquisa, na tentativa de aumentar os meus conhecimento técnicos de forma auto-didacta encontrei este glossário sobre suspensões.
Peço desculpa por estar em Inglês, mas com o tamanho dele iria demorar algum tempo a fazer a tradução.
Para quem não tiver conhecimentos de Inglês suficientes pode sempre efectuar a tradução em: http://www.google.com/translate_t
Espero que o mesmo seja util.

leg) and the height of the oil inside of the leg. The fork must be completely extended in order to
get an accurate measurement.

stem, and steer tubes which allows for the lightest weight and strongest design in 170mm single
