摘要: A bicycle crank assembly is provided with a first sprocket (14), a second sprocket (16), a crank arm (12), a sprocket fixing structure (70) and an alignment tube (76). The first sprocket (12) includes a plurality of first teeth (36) and at least one first mounting portion having a first mounting opening (40). The second sprocket (16) includes a plurality of second teeth (42) and at least one second mounting portion having a second mounting opening (46). The crank arm (12) includes at least one sprocket attachment portion having a third mounting opening (60). The sprocket fixing structure (70) secures the first and second sprockets (14, 16) to the crank arm (12) via the first, second and third mounting openings (40, 46, 60). The alignment tube (76) extends through at least two of the first, second and third mounting openings (40, 46, 60).

摘要: A bicycle crank assembly is provided with a crank arm including a front side surface and a back side surface. The crank arm has a crank axle mounting portion with a crank axle receiving opening defined by an axle coupling structure. The axle coupling structure at least includes a plurality of full length splines and at least one short spline. The full length splines extends completely in an axial direction of the crank axle receiving opening from a first axial end edge to a second axial end edge. The short spline extends in the axial direction with a truncated end positioned adjacent one of the first and second axial end edges such that the at least one short spline does not extend completely from the other of the first and second axial end edges to the one of the first and second axial end edges.
