Using this mudguard set is a breeze. First, find a trekking or city bike with 26' to 28' tires and a seat tube diameter between 28 to 32 mm. Then, use the universal attachment and clip holder to install the mudguards on your bike. The initial setup might take a bit of time, but once it's done, you can easily attach and remove the mudguards without any tools. When it comes to maintenance, just wash the mudguards with mild soap and water after a muddy ride. Avoid using abrasive cleaners as they can damage the impact - resistant high - performance plastic. Store the mudguards in a cool, dry place when not in use to keep them in good condition.
