Using the Sendit Caddy is a breeze. First, find a suitable spot on your bike frame or seatpost to attach the strap. Make sure it's tight and secure so it won't come loose during your ride. Open the three labeled compartments and neatly place your tire repair items inside. You can put the 25g CO2 cartridge, the 29” mountain bike tube, a small multi - tool, and tire levers in there. When you're out on the trail and need to use your repair tools, just open the relevant compartment. As for maintenance, after your ride, check the strap for any signs of wear and tear. If it gets dirty, you can gently clean it with a damp cloth. Keep it in a dry place when not in use to ensure its durability. And always double - check that the rubberized elastics are still providing good grip.
