The suspension has an anti-rotation spring (2) fixed on top of the saddle tube (4) and around the saddle rod (5) locking them at the required height. A collar (1) welded to the spring allows it to be fixed on top of the saddle tube along the same axis by a bolt (6). The welded collar enables saddle rod to be locked at the desired height. The anti-rotation spring has a diameter greater than the saddle rod so that it can be introduced inside it and made solid. The collar is held in tension by the bolt which fastens into a spindle (7), threaded in its horizontal centre, and is locked across the handlebars (8).
