Bicycle wheel to counteract the leading spokes. When forward torque is applied (i.e., during acceleration ), the trailing spokes experience a higher tension, while leading spokes are relieved, thus forcing the rim to rotate. While braking, leading spokes tighten and trailing spokes are relieved. The wheel can thus transfer the hub torque in either direction with the least amount of change in spoke tension, allowing the wheel to stay true while torque is applied. Wheels that are not required to transfer any significant amount of torque from the hub to the rim are often laced radially. Here, the spokes leave the hub
Rim (wheel) rim and then being welded together. The disk is welded in place such that the center of the wheel is equal to the center of the hub. The distance between the centerline of the rim and the mounting plane of the wheel is called the "offset" and can be positive, negative, or zero. One-piece rim and wheel assemblies (see image) may be obtained by casting or forging. The terms "wheel" and "rim" are often incorrectly used synonymously, as in decorative wheels being called rims. Used broadly, or used figuratively, the word "rim" can mean the outer edge of any circular
