Improvements in rear bicycle wheels are disclosed. The improvements afford more balanced torque transmission as between the proximal spokes, adjacent to the multiple sprockets and the distal spokes which are opposite from the sprockets. In one embodiment, torque balancing is achieved by providing the hub with a distal hub flange which has a diameter which is substantially larger than the proximal hub flange. Excellent results have been achieved in a wheel with a hub having a proximal hub flange with a diameter of X and a distal hub flange with a diameter of approximately 1.5 X. According to another embodiment, a wheel according to the present invention is provided with radially oriented proximal spokes and tangentially oriented distal spokes. This shifts the majority of the torque transmission tasks to the distal spokes which, as noted above, are under less tension than proximal spokes under static conditions. In yet another embodiment, a wheel according to the invention includes a novel hub in which torque is transmitted to the hub at a point between the distal and proximal hub flanges, but closer to the distal hub flanges.
