<p>The saddle tube is for bicycles, and comprises a saddle tube, a head and a saddle mounting truck. The truck (3) pivots freely on the head (2) on a transverse axis (4), and has lengthwise extensions on both sides of the latter. Similar lengthwise extensions (2c, 2d) are provided on the head and screws (8) in them act against the truck extensions (3g) so as to adjust the saddle angle independently of its lengthwise adjustment, and lock it firmly by lever action on both sides of the pivot axis.</p> |
