A replaceable replacement spindle assembly for both drive (tractor) axles and trailer axles comprises a spindle and seal ring. The spindle is an elongate cylinder having inner and outer bearing surfaces and a threaded portion at one end. The seal ring is a short annular or tubular component having a circular opening sized to achieve an interference fit on a portion of the spindle adjacent the inner bearing surface. The interfering surfaces of the spindle and the seal ring are complementarily dimensioned and tapered so that the surfaces contact when the spindle is properly positioned in the seal ring. Adjacent the end of the spindle opposite the bearing surfaces and threads is an end region with features such as openings or a channel which receive complementary fasteners such as plugs, short bolts or a through bolt.

A dropout assembly comprises a first dropout that includes a first through hole configured to receive an axle for a bicycle wheel. The dropout assembly also comprises a second dropout that includes a second through hole and a mounting surface. The second through hole is configured to receive the axle for the bicycle wheel. The dropout assembly also includes a rotational control mechanism that is configured to mount to the mounting surface of the second dropout. The rotational control mechanism includes a nut and a nut cover.

A bicycle axle is provided, including a mandrel and a sleeve member. The mandrel defines an axial direction and includes an axial rod, a head portion radially protruding from an end of the axial rod and an engaging portion radially protruding from the axial rod and being axially spaced apart from the head portion. The sleeve member is sleeved around the head portion and includes a flange radially extending inwardly. At least part of the flange is located between the head portion and the engaging portion and is abuttable against the head portion and the engaging portion in the axial direction.
