Patent ID: 8024992

Claim:
A saddle and/or handlebar height adjustment device, comprising: a tubular element having one end fixed to a saddle and/or handlebar and another end coupled to a support element; a support element; a threaded ring having an internal thread, said threaded ring coupling said tubular element to said support element, said threaded ring fixed to one of said tubular element and support element so as to be rotatable, and longitudinally fixed, with respect thereto and threadedly connected to the other of said tubular element and support element so as to be longitudinally adjustable with respect thereto upon relative rotation thereof, said internal thread terminating at a location spaced from an opening of said threaded ring to which the other of the tubular element and support element is fixed; and alignment means provided on said tubular element and support element for maintaining the relative rotational positions of said tubular element and support element upon relative rotation of said threaded ring and said other of said tubular element and support element to which said threaded ring is threadedly connected; whereby rotation of said threaded ring relative to said tubular element and support element results in longitudinal movement of said tubular element relative to said support element but no relative rotational movement between said tubular element and said support element.
