Using these wheels is easy. First, make sure your bike is compatible with a 29 - inch wheel and a 12 x 142mm rear axle. If you want to use tubeless tires, install them following the tubeless tire installation guide. When riding, these wheels can handle different terrains like mountains and gravel roads well. As for maintenance, regularly check the tire pressure. Keep the wheels clean by washing them with mild soap and water after rides, especially if you've been in dirty or muddy conditions. Avoid using harsh chemicals that could damage the finish. If you notice any unusual noises or play in the hub, it's a good idea to have a professional bike mechanic take a look.
