  • Publication number: 20090108644
    Abstract: A saddle with proper deformability is provided. The saddle comprises a base, a pad, and a fastening device adapted to fasten the base and pad together. Therein, the materials of the pad comprise Ethylene-vinyl acetate (EVA). Thereby, the saddle of this invention is adapted to deform appropriately according to the buttocks and the crotches of a cyclist and to absorb the vibration that is experienced during the ride, so that the comfort of the saddle is greatly improved.

  • Publication number: 20070246978
    Abstract: A bicycle saddle has a base frame and a pad covered on the base frame. The base frame has a narrow front portion with a plurality of first lower ventholes and a wide rear portion with a plurality of second lower ventholes. The pad has a plurality of first and second upper ventholes which are arranged in such a way that each upper venthole respectively corresponds to each lower venthole to together define an air channel. Whereby ambient air can flow through the whole areas of the saddle contacting with the buttocks and inner thighs of the cyclist during cycling to provide a better ventilation effect.
