Abstract: A handlebar shock absorber is provided. The handlebar shock absorber includes a shock-absorbing cylinder, a knuckle having a lower pivot mount for attachment to the cylinder, and an arm assembly pivotably coupled to the knuckle and including an upper pivot mount for attachment to the cylinder. The cylinder includes an adjustable pre-stressed length to elevate or lower the position of the arm assembly relative to the knuckle. The knuckle is adapted for attachment to a bicycle steering tube, and the arm assembly is adapted for attachment to a bicycle handlebar. In use, the shock-absorbing cylinder dampens movement of the handlebar relative to the steering tube to provide an enhanced ride to the cyclist over rough terrain.
