How to Easily Change Handlebars on Your Mountain Bike
To change handlebars on a mountain bike, first, remove the grip from the existing handlebars with the help of a flathead screwdriver. Then unscrew the bolts on the stem, and remove the handlebars from the stem. Replace the new handlebars on the stem and tighten the bolts. Finally, place the grips on the new handlebars and adjust as necessary.
