Using your Norco Fluid HT 2 is a breeze. First, adjust the seat height and suspension according to your preference and the type of trail you'll be riding. When you're out on the trail, use the Shimano Deore 11 - Speed drivetrain to shift gears smoothly and adapt to different terrains. The dropper post can be adjusted to lower your center of gravity on descents for better control. As for maintenance, regularly clean your bike after each ride, especially the chain and gears. Check the tire pressure before every ride to ensure a smooth and safe journey. Also, keep an eye on the brakes and suspension, and if you notice any issues, have them serviced by a professional. With proper care, your Norco Fluid HT 2 will serve you well for many adventures.
