Using this stem raiser is a breeze. First, make sure your bike has an Ahead type stem. Then, remove the existing stem from the frame. Place the stem raiser between the frame and the stem, and then reinstall the stem. Tighten all the bolts carefully to ensure a secure fit. When it comes to maintenance, it's a good idea to check the tightness of the bolts regularly, especially after long rides. Keep the stem raiser clean by wiping it with a soft cloth. Avoid using harsh chemicals as they may damage the cold - forged aluminium surface. If you notice any signs of wear or damage, replace the stem raiser promptly to keep your bike in top condition.
