Using your MSW 25° Bike Stem is straightforward. First, select the appropriate length between 60 - 110mm according to your riding needs. Install it using the 4 - bolt faceplate, which is easy to handle. When riding, make sure the stem is properly tightened. As for maintenance, keep it clean by wiping it regularly with a soft cloth. Avoid using abrasive cleaners as they may damage the anodized black finish. Check the tightness of the bolts periodically to ensure safety. If you notice any signs of wear or damage, it's best to replace the stem to keep your bike in top - notch condition.
