Using the Topeak Tri - Cage is super easy. First, mount it on your saddle carrier following the instructions. Then, put your water bottle (up to 750mL) into the cage. When you need a drink, just use the 'forward - release' design to quickly get your bottle out. Make sure to check the compatibility of your bottle diameter (72mm - 74mm is recommended). You can attach your Ninja T Road tool case, Ninja CO2 inflator, or Ninja Pouch Road spare tube carrier to the integrated bottom mount. Keep the cage clean by washing it with mild soap and water regularly. Avoid using harsh chemicals as they may damage the engineering - grade polymer material. If you're not using the tire levers, store them safely to prevent loss. That's all you need to know to make the most of your Topeak Tri - Cage!
