ABSTRACT:
A component for use in conjunction with a bicycle brake member or block, being arranged to contact a bicycle wheel rim in advance of the brake block as the brake is applied, so as to clean the wheel rim of water and/or dirt to improve braking performance. The component may be formed integrally with the brake block or separately for attachment thereto. The component includes a scraper element, whose end surface is arranged to contact the wheel rim. The scraper element is connected to the main body of the component by a flexible hinge portion, which allows the scraper element to flex about the hinge portion, so that as the brake is applied to bring the brake block into contact with the wheel rim, the scraper element flexes against the bias of the hinge portion to bias the scraper element into contact with the wheel rim. The scraper element, hinge portion and main body are all formed integrally of plastic material, preferably injection molded in glass-reinforced nylon.
