How to Effortlessly Raise Handlebars on Your Mountain Bike for Comfort and Convenience
To raise handlebars on a mountain bike, locate the stem bolts that attach the handlebars to the bike frame, and loosen them with an Allen wrench. Adjust the stem to the desired height and tighten the bolts back up. Adjusting the stem angle may also change the height of the handlebars. For further adjustments, consider buying a stem with a different length and angle that will accommodate the desired height.
