A handlebar stem assembly includes a stem having a ridge axially on a top thereof and a sliding member is slidably mounted to the ridge and cooperates with a first end of the stem to define a handlebar hole in which the handlebar is secured. A passage is defined in a second end of the stem so as to be connected with the steerering tube of a front fork. A pivotable member is pivotably connected to the sliding member and urged between the sliding member and a portion of the stem. A spring is biased between the ridge and the sliding member. The sliding member can be moved toward second end of the stem to open the handlebar hole while the pivotable member is pivoted relative to the sliding member. The handlebar hole is partially closed by releasing the sliding member.
