Abstract
A bicycle stem includes a steerer tube base including a pivotal end having a pivotal hole and two blocking devices provided in the pivotal end and slightly protruding from an inner side of the pivotal hole. A clamp arm includes a coupled end pivotally coupled to the pivotal end. A lock unit includes two lock sleeves, an engaged bolt disposed in the pivotal hole of the pivotal end and a blocking element for preventing the engaged bolt from detaching from the pivotal end. The lock unit is operable between a first position and a second position. In the first position of the lock unit, the clamp arm is fixed and can not pivot with respect to the steerer tube base, and in the second position of the lock unit, the clamp arm is able to pivot with respect to the steerer tube base.
