Abstract: A saddle support device includes a resilient support fixed on an upper end of a seat post of a bicycle. A base, a carriage and a yoke are provided in series on the support and each has a hole and are clamped together by a bolt. A pair of saddle frames of a saddle are received between the carriage and the yoke. A cushion is received in the support. The resilient support and the cushion absorb a shock or a vibration which may be transferred to a rider so that the rider may feel more comfortable.
