Using your Cirrus Kinekt Suspension Stem is easy. First, make sure it's properly installed on your bike according to the manufacturer's instructions. You can adjust the stem to your liking by choosing one of the three provided springs (Soft, Medium, or Firm) based on your riding style and the terrain you'll be on. Changing the spring is a breeze. When riding, enjoy the comfort and control it provides, as it reduces vibrations from rough ground. As for maintenance, regularly check the stem for any signs of wear or damage. Keep it clean by wiping it down after rides, especially if you've been in muddy or dusty conditions. And if you notice any issues with the movement or performance, don't hesitate to reach out to customer support.
