Abstract
Carbon fiber bicycle wheels are formed from parts cut from carbon fiber cloth and then joined together to form a rim, sidewalls, spokes, flanges and a center tunnel on which the flanges are mounted. The parts are then assembled, bonded together, and cured to form a wheel. During assembly, the spokes and the wheel are placed in tension by moving the flanges outwardly on the center tunnel after assembly and then bonding them in place to stiffen and strengthen the wheel. The spokes of the drive side of the rear wheel are specially shaped to accommodate torque transfer forces generated by pedaling.
