Fenders Fenders protect you and your bike from water, mud, and debris, keeping your ride cleaner and more comfortable. Choose between clip-on fenders for easy installation or full-coverage fenders for maximum protection. Material matters—plastic fenders are lightweight and affordable, while metal fenders offer more durability. Look for adjustable fender designs to ensure a good fit on your bike.
