Spoked rear wheel for a bicycle
摘要:
A spoked rear wheel for a bicycle that may improve the rigidity of the wheel, while the weight of the spokes is restrained. The spoke rear wheel of the present invention comprises: a rim (10); a hub (20) having a hub axle (21), a first spoke attachment portion (22), and a second spoke attachment portion (23) spaced from the first spoke attachment portion; a first set of spokes (30) for connecting the rim to the first spoke attachment portion (22); and a second set of spokes (40) for connecting the rim to the second spoke attachment portion (23); the first set of spokes include a first spoke (31) and a second spoke (32); the second spoke includes a rim end portion (320) connected to the rim, a hub edge portion (321) connected to the first spoke attachment portion (22), a second central portion (322) connected to the rim end portion and hub edge portion, and having a second cross-sectional area. The first spoke (31) includes a rim end portion (310) connected to the rim, a hub edge portion (311) connected to the first spoke attachment portion (22), a first central portion (312) connected to the rim end portion and hub edge portion, and having a first cross-sectional area which is greater than the second cross-sectional area.
