These mountain bike fenders are exactly what you need to stay clean on muddy trails! The set includes both front and rear fenders that fit 26-inch mountain bikes (they also work with 20, 22, and 24 inch models). The rear fender is about 55cm long and the front is 30cm, giving you solid coverage from wheel spray. They're made from durable PP material that can actually bend 360 degrees without breaking - super handy when you're navigating rough terrain. The quick release design means you can install or remove them in seconds without tools. No more arriving home with a muddy stripe up your back! The fenders effectively block mud, water, and debris from spraying up onto you and your bike. At about 230g for the set, they're lightweight enough not to weigh you down. Whether you're commuting in the rain or hitting muddy trails, these fenders keep you cleaner and more comfortable. Definitely a smart upgrade that makes riding in less-than-perfect conditions much more enjoyable!
