Using the Suntour Xct 29 Suspension Fork is quite straightforward. First, make sure it's properly installed on your NCM Prague 29' or Moscow 29' bike. You can adjust the pre - load on both the right and left sides according to your riding needs. For casual mountain biking, set it to a comfortable level. When riding, the fork will absorb shocks and bumps, giving you a smooth experience. As for maintenance, regularly clean the fork with a mild detergent and a soft cloth. Check the pre - load adjusters from time to time to ensure they are working properly. If you notice any unusual noises or reduced performance, it might be a good idea to take it to a professional bike mechanic. Also, avoid exposing the fork to extreme weather conditions for long periods as it could damage the components. And remember, the package doesn't include the Star Nut, so if you need it, you'll have to get it separately.
