Mountain bikes are not equipped with shields as standard. But most cyclists ride in any weather and in different places. To protect your clothes from dirt, it is advisable to buy shin guards for your bike. They often have universal mounts and fit on any type of bike. Choosing bicycle fenders can sometimes be a daunting task as there is a wide variety of fenders now available. Mountain bikes are mainly equipped with plastic fenders, which are not fixed by the bows to the wheel axle, as they interfere with the disc brakes. Mudguards for city and road bicycles come in steel and plastic, they are the best protection for clothes, since they are the longest. Wings are available as stationary and quick-detachable wings. Even for bicycles that have a two-crown fork, there are DH-bike fenders, in which the front fender is attached directly to the frame.
