How to effectively raise the stem on your mountain bike
To raise the stem on a mountain bike, you need to loosen the bolts on the steerer tube, carefully lift the stem and handlebar away from the steerer, and then insert spacers to increase the height. Once you’ve added the spacers, push the stem back into place, and re-tighten the bolts on the steerer tube. Remember to adjust the headset and ensure that your new stem height is properly aligned and tightened before cycling.
