1. A hub for a human-powered vehicle, the hub comprising:
a hub axle including a first inner abutment, the hub axle defining a rotational axis, the first inner abutment being integrally formed on an outer surface of the hub axle as an integrated part of the hub axle;
a rotating body rotatably mounted on the hub axle to rotate around the rotational axis, the rotating body including a first outer abutment;
a first bearing disposed between the hub axle and the rotating body in a radial direction with respect to the rotational axis to rotatably couple the rotating body to the hub axle, the first bearing including a first inner race halting a first axially facing portion abutting the first inner abutment of the hub axle, a first outer race having a first axially facing portion abutting the first outer abutment of the rotating body, and a plurality of first roller elements disposed between the first inner race and the first outer race;
an inner retainer coupled to the hub axle and abutting a second axially facing portion of the first inner race of the first bearing;
an outer retainer coupled to the rotating body and abutting a second axially facing portion of the first outer race of the first bearing; and
a second bearing disposed between the hub axle and the rotating both in a radial direction with respect to the rotational axis to rotatably couple the rotating body to the hub axle, the second bearing including a second inner race having a third axially facing portion facing a second inner abutment of the hub axle, a second outer race haling a third axially facing portion facing a second outer abutment of the rotating body, and a plurality of second rolling elements disposed between the second inner race and the second outer race,
the second inner abutment of the hub axle being axially spaced from the second inner race of the second bearing.
