Remember, when setting the height of your handlebars, personal preference and variations in physique will have an important effect. You should feel free to make adjustments until you find the position that allows you to ride comfortably for extended periods of time. In general, the higher the handlebar is set, the more upright you will sit.
NOTE: All handlebars have a minimum insertion mark. Make sure you don't raise your handlebars into a fixed position so high that you pull this mark up out of the frame. Below this point, it means that there is less than two inches of the handlebar stem remaining inside the frame, and the handlebars are susceptible to breaking which will cause a mean crash.
