How to Replace Your Mountain Bike Stem: A Step-by-Step Guide
To replace a mountain bike stem, start by loosening the bolts on the existing stem using an allen key or torque wrench. Once the bolts are loose, the stem should be able to be lifted out of the headset. Before installing the new stem, make sure it will fit your handlebars and frame properly. Then, slide the new stem onto the steerer tube and tighten the bolts to the recommended torque setting. Test the new stem to make sure it is secure before riding.
