Installation is straightforward with standard bicycle tools, making these spacers ideal for DIY maintenance. To install: 1. Remove the stem, top cap, and any existing spacers from your steerer tube. 2. Arrange the new spacers in your desired combination to achieve your preferred handlebar height. 3. Reattach the stem and top cap, tightening to the manufacturer’s recommended torque specifications to ensure a secure fit. Always double-check stem bolt tightness before riding to prevent movement or safety issues.
