Using the Topeak Cage Ninja Master+ Case SK is easy. First, decide which side you want to access your water bottle from and mount the cage accordingly. To add tools, a CO2 inflator kit, or an inner tube holder, use the interchangeable Cage Mount. When it comes to maintenance, simply clean it with mild soap and water regularly to keep it in good condition. Avoid using harsh chemicals as they might damage the engineering - grade polymer material. Also, make sure to check the compatibility of any additional accessories with the cage before attaching them.
