Structure for adjustably attaching a disc brake caliper to a bicycle frame

A structure for attaching a caliper of a disc brake system to a cycle frame with a pair of brake pads advanced by the caliper in operative engagement with a rotor of the disc brake system, the frame having a pair of threaded caliper mounting bores and the caliper having a mounting foot, the attaching structure comprising:

• mating concave and convex surfaces between the frame and a bottom of the caliper mounting foot to pivot the caliper about a pivoting axis with a pair of holes corresponding to the caliper mounting bores extending through the concave and convex surfaces;
• a pair of spaced slots on the caliper mounting foot extending transverse the pivoting axis and aligned with the holes and the mounting bores;
• and
• a pair of bolts axially received in the aligned slots, holes and threaded mounting bores, the bolts engaging the threaded mounting bores to maintain the pads of the caliper in a select orientation relative to the rotor.

An attachment structure for attaching a component to two mounts affixed to a bicycle frame to provide gimbaled movement of the component relative to the frame, the attachment structure comprising:

• a. mating concave and convex surfaces between the mounts and a bottom of the component for enabling hinged movement of the component relative to the mounts about a first axis with a hole extending between each of the mounts and the component through the concave and convex surfaces;
• b. a pair of spaced elongate slots on at least one of the component and the mounts extending transverse the first axis and each slot aligned with one of the holes through the concave and convex surfaces, the spaced slots being positioned relative to one another to enable pivoting of the component relative to the mounts about a second axis perpendicular to the first axis while the slots remain aligned with the holes through the concave and convex surfaces;
• and
• c. a pair of compression members each having a shaft extending through one of the holes and one of the elongate alignment slots, the compression members selectively compressing the mounts and the component together to fix them relative to one another.
