摘要

The saddle suspension has a thrust block (12) fitted to the saddle tube (1), at a clearance from the piston (8) inside the tube. There is a stressed levelling spring (13) between the thrust block and the piston. The saddle is fixed to the free end of the saddle rod (6). The top end (4) of the saddle tube has a pedestal bearing on the tube side, with a bearing pin (21) serving as an axis. There is a guide roller (19,20) on each end of the pin. The piston may be screwed to the saddle rod, and the thrust block may be in the form of a ring.
