Handlebars and Stem
Most handlebars are held in the stem by a binder bolt. Newer models may have a design with two bolts. These make the handlebars easier to remove from the stem by enabling the handlebars to be lifted straight off as opposed to slid out from the side.
To adjust handlebar position, follow these steps (see Figure 5-10).
