Using the SHIMANO XTR RT - MT900 disc brake rotors is easy. First, make sure your bike is compatible with the CENTER LOCK mounting system. Then, use the spine mount and lock ring to quickly install the rotor. When riding, you'll notice the great stopping power, especially in aggressive situations. As for maintenance, regularly check the rotor for any signs of wear or damage. If it gets dirty, clean it gently with a soft cloth and mild cleaner. Avoid using abrasive materials that could scratch the rotor. Also, be careful when handling the rotors to prevent bending. On long downhill rides, the rotors will dissipate heat well, but try not to over - brake continuously to keep them in good condition.
