Using the Lezyne M - Caddy Sport Kit is a breeze. First, attach the M - Caddy saddle bag to your bike's saddle rails and seatpost using the Velcro straps. Make sure it's secure so it won't fall off during your ride. When you need to make a repair, unzip the water - resistant zipper using the large pull loop. You can easily find the tools you need in the labeled organizational pockets. The RAP II - 6 multi - tool can handle most common bike repair tasks. Use the Smart Kit for fixing flat tires quickly. And if you need to pump up your tires, grab the Sport Drive HP hand pump. For maintenance, keep the saddle bag clean by wiping it with a damp cloth. Make sure the Velcro straps aren't dirty so they can stick well. Check the reflective logos and loops regularly to ensure they're visible at night. When not in use, store the kit in a dry place to prevent damage to the tools and the bag.
