Handlebar and Stem
The bicycle may have different styles of handlebar stems. One style mounts inside the fork while the other mounts around the outside of the fork. Follow the instructions for the style that you have.
Assembly
1. Assemble the stem to the fork:
Inside mount style
-If necessary, assemble the stem bolt [4], washer [10], and wedge nut [11] to the stem [1]
-Point the stem [1] toward the front of the bicycle
WARNING: To prevent steering system 
damage and possible loss of control, the
(minimum insertion) mark [3] on the stem must be inside the locknut.
-Tighten the stem bolt [4] just enough that the stem will not fall into the locknut.
Outside mount style
-If necessary, loosen the top bolt (1) of the stem (2) and the stem bolt(s) [3] only just far enough so the stem can turn on the fork
-Point the stem toward the front of the bicycle
-Tighten the top bolt of the stem
-Tighten the stem bolt(s) equally.
2.Assemble the handlebar to the stem:
-Put the handlebar [5] into the stem, but do not tighten the handlebar clamp [6] at this time.
