Abstract

Brake mounts for bicycles are described herein. The brake mounts are for coupling a brake caliper to a bicycle. An example brake mount includes a bracket having a first side and a second side opposite the first side. The bracket has bores to receive fasteners to couple the brake caliper to the bracket. The brake mount includes a sleeve extending from the first side of the bracket. An opening extends through the sleeve and the bracket. The opening is to receive an axle of a hub assembly of the bicycle. The sleeve is to extend into an axle opening in a frame of the bicycle. A distal end of the sleeve is threaded. The brake mount also includes a nut to be threadably coupled to the distal end of the sleeve when the sleeve is inserted into the axle opening in the frame e.

First claim

What is claimed is:

1. A brake mount for coupling a brake caliper to a bicycle, the brake mount comprising:
a post to be coupled to and extend from an inboard side of a frame of the bicycle;
a bracket having:
bores to receive fasteners to couple the brake caliper to the bracket;
a first opening to receive an axle of a hub assembly of the bicycle;
a second opening, the post to extend through the second opening when the bracket is installed on the bicycle;
a gap extending between the second opening and a peripheral edge of the bracket; and
a fastener opening extending into the bracket and across the gap; and

a clamp bolt to be threadably inserted into the fastener opening to reduce an inner diameter of the second opening to clamp the bracket onto the post.

2. The brake mount of claim 1 , wherein the second opening is elongated in a radial direction from a central axis of the first opening.

3. The brake mount of claim 1 , further including a sleeve to be disposed in the first opening such that an inner surface of the bracket is engaged with an outer surface of the sleeve.

4. The brake mount of claim 3 , wherein the outer surface of the sleeve has a first shoulder and the inner surface of the bracket has a second shoulder to be engaged by the first shoulder.

5. The brake mount of claim 1 , further including a sleeve to be disposed around the post to increase a contact area between the bracket and the post.

6. A hub assembly of a bicycle, the hub assembly comprising:
a hub;
a brake rotor coupled to and rotatable with the hub;
a bracket having bores to receive fasteners to couple a brake caliper to the bracket, the bracket having a first side, a second side, and an opening extending between the first and second sides;
a sleeve extending from the first side of the bracket, the sleeve coaxial with the opening in the bracket; and
an axle extending through the sleeve, the opening in the bracket, the brake rotor, and the hub, the axle having a head engaged with the sleeve such that the sleeve and the bracket are axially clamped between the head of the axle and an end of the hub,
wherein the sleeve has a length such that when the hub assembly is coupled to the bicycle, the sleeve extends through an axle opening in a frame of the bicycle.

7. The hub assembly of claim 6 , wherein the sleeve has a distal end, wherein an inner surface of the sleeve has a shoulder near the distal end, and wherein the head of the axle is engaged with the shoulder.

8. The hub assembly of claim 7 , wherein the distal end of the sleeve is threaded, the hub assembly further including a nut to be threaded onto the distal end of the sleeve.

9. The hub assembly of claim 6 , further including a washer around the sleeve, the washer to be disposed between the bracket and an inboard side of a frame of the bicycle when the hub assembly is coupled to the bicycle.

10. The hub assembly of claim 9 , wherein the washer is constructed of a compliant material.

11. The hub assembly of claim 9 , wherein an outer peripheral edge of the washer is tapered.

12. The hub assembly of claim 9 , wherein the washer has a spheric surface.
