If you know that it may rain in the place where you are heading, the bike ought to be equipped with long mudguards. In the best case scenario, they are made of plastic reinforced with aluminium, and mounted to the frame using wires. Such a solution is both lightweight and durable. It is also worth supplying the front mudguard with a rubber protector. Even if not particularly attractive, this solution greatly improves cycling comfort in the rain, protecting shoes and legs against water and mud. Such rubber attachments must be made at home, as they are not available in stores.
