A bicycle steering bearing assembly includes features for internal routing of actuator cables. Apertures through the elements of the steerer bearing assembly are configured to provide for the maximum actuator cable size while providing uniform application of forces to the steerer tube and upper bearing. Such apertures may be angled or partially angled from vertical, and may be or may include tapered sections. The apertures may also include a relief feature.

A motorcycle fork has an upper tree; a lower tree; a steering neck; and a steering stem. The steering stem is connected to the upper tree at a steering stem upper end, and is connected to the lower tree at a steering stem a lower end, and passes through the steering neck. The steering stem is oriented to a steering neck centerline in a first mode. A neck upper bearing race seat is formed on an upper portion of the steering neck. A neck lower bearing race seat is formed on a lower portion of the steering neck. An upper bearing race receives an upper bearing. The upper bearing race is mounted in the neck upper bearing race seat in the first mode. A lower bearing race receives a lower bearing. The lower bearing race is mounted in the neck lower bearing race seat in the first mode.

An assembly comprising: a core in the form of a toroid; and at least one washer overlying the core, the washer comprising a polymer, wherein the washer has an arcuate cross-section so as to have a shape complementary to the core.

The motor vehicle (1) comprises at least one rear driving wheel (5) and two front steered wheels (7′, 7″). A tilting four bar linkage (11) allows the motor vehicle to perform a tilting movement, for example, when cornering. Support arms (21′, 21″) for front steered wheels (7′, 7″), which rotate around steering axes (21A′, 21A″) and are joined to each other by a steering bar (23), are associated with the tilting four bar linkage Each wheel is constrained to the respective support arm with the interposition of a suspension (33; 33″). A tilting locking device comprises a brake (53′, 53″) which locks the springing movement of the respective suspension and the tilting movement of the four bar linkage.

A bicycle bearing system comprising: an integrated cup, the integrated cup having an outer diameter; a plurality of rolling elements configured to abut and rotate against a first race groove located on an inner surface of the integrated cup; a second race groove configured to abut and rotate about the plurality of rolling elements, the second race groove located on an inner surface of the inner race, the inner race having an inner diameter; where the rolling elements do not have a separate outer race, but rather the inner surface of the integrated cup acts as the outer race to the rolling elements; and where the rolling elements, integrated cup and inner race are axially locked when assembled as a single cartridge unit due to the geometry of the rolling elements, first race groove and second race groove.
