Using this mini tool is a breeze. When you encounter mid - ride mechanical issues, just take it out from the PRO Smart Bottle Cage where it's stored. You can use the Allen and Torx keys on it to make adjustments to your bike parts. For best results, make sure to turn the keys gently but firmly for precise adjustments. As for maintenance, keep it dry after use. If it gets dirty, you can use a clean cloth to wipe it. Avoid using harsh chemicals as they might damage the hardened steel tips of the bits. Store it back in the Smart Bottle Cage when not in use so it's always handy for your next ride.
