Using your Aris 26mm stem is easy. First, make sure your bike's handlebar and steerer tube are clean and dry. Select the right length of the stem for your comfort and riding style. Attach the stem to the steerer tube and use the four - bolt faceplate to secure the handlebar tightly. When riding, be aware of any unusual noises or looseness. If you notice anything, stop and check the bolts' tightness. For maintenance, regularly clean the stem with a mild soap and water solution. Avoid using abrasive cleaners that could damage the aluminum surface. After cleaning, dry it thoroughly to prevent rust and corrosion. Check the bolts periodically to ensure they remain tight, as vibrations from riding can sometimes cause them to loosen.
