Topeak's DeFender M1 front fender offers durable rain and mud protection on wet and sloppy rides for your 27.5- or 29-inch wheeled bike. It's incredibly light and easy-to-use, too. The M1 installs easily to any standard fork, even reverse arch designs and seamlessly integrates with the front end of your bike. The quick-release attachments allow the DeFender to be installed and removed in seconds.
