ABSTRACT:
A caliper brake for wide-tire mountain bicycles. Each caliper arm is pivotally mounted to a stationary pivot post of the bicycle frame via a cylindrical bushing to which the arm is press fitted. A return spring is retained around the pivot post in a normally stationary portion enabling purposeful adjustment. A brake shoe holder is mounted on one end of the caliper arm, and a roller-mounting post is secured to the other end. A cam roller is mounted rotatably on the roller mounting post by a low-friction bearing and has a circumferential groove engaging a cammed edge of a cam plate, to which a brake-actuating cable is secured. The brake shoe holder is preferably asymmetrical and is mounted for adjustment lengthwise of the caliper arm and for rotation around it and is also made adjustable as to the spacing from the caliper arm and as to the rotational position around an axis perpendicular to that arm.
