If your bicycle handlebar is not straight, like the picture below, follow these instructions to straighten things out!
Crooked Handlebars are Easy to Fix
1. Loosen the Pinch Bolts
There are two bolts on the back size of the stem. They face opposite directions. These are the pinch bolts. Loosen both pinch bolts. You only need to loosen them a couple of turns.
