Abstract: An arrangement 10 includes at least one straight rod 11 which is connected to the saddle support frame or to the support 20 carrying the saddle support frame. The arrangement 10 prevents rotation of the saddle about the longitudinal axis of the support 20 and limits the stroke of the support in the rearward inclined tube of the cycle frame and therefore fixes the highest elevation to which the saddle can be adjusted. The arrangement also prevents theft of the assembly comprising the saddle and its support. In a case of a closed frame, the arrangement 10 includes a U-shaped rod defined by two legs on respective sides of the transverse tube 32 of the cycle frame. The U-shaped rod includes a bight portion 17 which connects the two lower ends of the rod 11. The bight portion 17 limits the stroke of the support 20 and makes theft of the assembly of saddle and support difficult.
