ABSTRACT:
An apparatus for adjusting the position of a handlebar on a bicycle or the like having a base member, an upper link, a lower link, and a intermediate member forming a parallelogram type link. A protrusion formed on the lower link extends into and slidably contacts a tracking slot formed in the upper link. A locking means for fixing the upper and lower links has a locking pin disposed in a bore formed in the upper link and extending through one of a plurality of holes formed in the protrusion of the lower link. The locking pin defines a locked position when extending into one of the plurality of holes and an unlocked position when released. The pin is biased in the locked position. A release lever is disposed on the upper link having a operating portion for grasping by a rider and a locking pin portion for engaging the locking pin.
