How to use: First, if you face mid - ride mechanical problems, take the tool out of the Smart Bottle Cage. You can use the Allan, Torx, and screwdriver keys for various adjustments on your bike. The chain tool is for dealing with chain - related issues, and you can store a spare chain link in the designated storage points. When using the bits, slot them into the lever for better tensioning power. Attention: Don't use excessive force when making adjustments to avoid damaging the tool or your bike. Maintenance: After each use, wipe the tool clean with a dry cloth. Keep it in a dry place to prevent rusting. If any part of the tool gets damaged, it's recommended to replace it as soon as possible.
