Using the Roval Rapide C 38 Carbon Wheelset is easy. Just install them on your 700c bike according to the standard wheel - installation process. When riding, you'll notice the smooth handling and great climbing ability right away. Whether you're on gravel or asphalt, these wheels will perform well. As for maintenance, regularly check the tire pressure to ensure optimal performance and safety. You can use a regular bike pump to inflate the tires. Also, after a long ride or if the wheels get dirty, clean them with a mild soap and water solution. Avoid using harsh chemicals as they might damage the carbon rims. When storing the wheels, keep them in a dry place away from direct sunlight to prevent any potential damage to the carbon fiber. And always make sure the wheels are properly tightened before each ride to avoid any safety issues.
