New for 2010 the lightest fenders in the world for your road bike. These fenders mount up quickly and offer unmatched protection. At the same time the ground-breaking styling along with racer weight sets a new standard. New engineering comes to fenders with lightweight self-centering pilestrip brushes that elminate rubbing and noise completely. Mounting is completed with simple rubber o-rings at the stay/fork and a reuseable nylon tie at the brake fixing location. These fenders are designed with unique fasteners that will detach upon any instance of stoppage or unwanted debris for safety. Fender struts are made of a lightweight synthetic fiber that will breakaway prior to any spoke damage if an accident should occur. 25mm is the maximum general tire size for these fenders.
