Abstract: Embodiments of the present invention are directed generally to devices for imparting preload on mechanical structures. More specifically, embodiments of the present invention are directed to a preload device that is relatively lightweight, simple to use and inexpensive to manufacture and that is specifically configured for imparting a preload on bearing interfaces coupling concentrically arranged tubes. In some embodiments, a steerer tube of a bicycle fork and a head tube of a bicycle frame are the concentrically arranged tubes.

Abstract: A crankset comprises an axle assembly, a drive-side crankarm, and a non-drive crankarm. The drive-side crankarm is attached at a first end portion thereof to a first end portion of the axle assembly. The non-drive crankarm is attached at a first end portion thereof to a second end portion of the axle assembly. Each one of the crankarms has a plurality of longitudinal holes therein extending between the first and second end portions thereof. The longitudinal holes each extend through an end face of a respective one of the crankarms at the first end portion thereof. The drive-side crankarm is bent inwardly toward the second end portion of the axle assembly after the longitudinal holes are formed therein. Only one of the longitudinal holes of the drive-side crankarm intersects an axle fastener engagement hole that extends through the first end portion of the drive-side crankarm.

Abstract: A bicycle brake assembly comprises brake arms, axles, a force application linkage structure, and a movement control linkage member. The brake arms are each pivotably mounted at the central portion thereof on a respective one of the axles. The force application linkage structure has a first force transmitting member connected to the first brake arm and a second force transmitting member thereof connected to the second brake arm. The movement control linkage member is coupled between the first one of the force transmitting members of the force application linkage structure and the second one of the axles for controlling movement the brake arms relative to each other for a given displacement of the force application linkage structure.

Abstract: A light weight brake assembly for bicycles is disclosed. Some embodiments of the invention are designed to enhance assembly adjustability, for example to accommodate geometric variations that occur with various bicycle frame and wheel geometries. Some embodiments of the invention are designed to allow for a brake leverage that can be non-linear and capable of multiplying during brake actuation so that braking force increases more rapidly than brake lever force applied by the user. Some embodiments of the invention are designed to provide a brake sensitivity that is adjustable in use. Some embodiments provide for a quick-release functionality, for example by quickly increasing the gap between the two brake pads so that the wheel can be easily/quickly removed.

Abstract: A brake shoe for holding a brake pad of a bicycle brake assembly has opposed first brake shoe undercuts at a first end portion of the brake shoe and opposed second brake shoe undercuts at a second end portion of the brake shoe. A slot is defined between the opposed first brake shoe undercuts and a slot is defined between the opposed second brake shoe undercuts. An edge wall is connected to all of the undercuts and a sidewall is connected to the edge wall. A brake pad receiving channel extends along the length of the brake shoe between the sidewall and all of the brake shoe undercuts. A brake pad insertion passage jointly intersecting the slot defined between the opposed first brake shoe undercuts and the slot defined between the opposed second brake shoe undercuts.
