Using the BC18 is easy. First, install the bottle cage on your bike's standard 64mm mounting bracket, choosing whether you want it on the left or right side according to your preference. When you're out on the trail and face a mechanical issue, simply reach for the tools in the kit. Use the mini - tool for general repairs, the tire lever to change a flat tire, the CO2 inflator to quickly inflate your tires, the chain tool for chain repairs, and the spoke wrenches for spoke adjustments. As for maintenance, keep the tools clean after each use. Wipe them down to prevent dirt and grime from building up. Store the kit in a dry place to avoid rusting. Make sure to check the CO2 cartridge regularly and replace it if it's empty. With proper use and care, the BC18 will be your reliable companion on every ride.
