Frase: Toolless 15 mm skewer system optimizes rigidity and weight

Um "skewer" de treinamento deve ser usado juntamente com o rolo. O "skewer", incluso na maioria dos rolos encontrados à venda, é usado no lugar do "skewer" normal do seu eixo dianteiro, para prevenir que seja arranhado pelas braçadeiras do rolo de treinamento.

A quick release skewer is a mechanism for attaching a wheel to a bicycle. It consists of a rod threaded on one end and with a lever operated cam assembly on the other. The rod is inserted into the hollow axle of the wheel, a special nut is threaded on, and the lever is closed to tighten the cam and secure the wheel to the fork. Wheels equipped with quick release mechanisms can be removed from the bicycle frame and replaced without using tools by opening and closing the cam lever, thus more quickly than wheels with solid axles and nuts. On the negative side, a quick-release hub renders a wheel more vulnerable to theft and care must be taken to ensure that the mechanism is properly tightened.
