Using the Lezyne Roll Caddy is easy. First, roll it out to its full size, which is 270 x 260 mm. You can then place your large cycling accessories inside, like extra tubes or a multi - tool. Put your small valuables, such as keys or a credit card, in the internal zippered pocket. Once you've loaded your items, roll it up and secure it to the seat rails with the straps. When it comes to maintenance, just wipe it down with a damp cloth if it gets dirty. Avoid using harsh chemicals as they might damage the nylon material. Also, make sure to check the straps regularly to ensure they're still in good condition and can hold the caddy securely. And remember, don't overfill it beyond its 0.6L cargo capacity to keep it functioning well.
