A spoke for an at least partially muscle-powered bicycle and wheel including a spoke where the spoke comprises a spoke body with a hub-side, first end and a rim-side, second end and the first end and the second end are remote from one another. The spoke body is elongated and includes at least one first center region disposed closer to the first end than to the second end, and at least one second center region disposed closer to the second end than to the first end. The first center region and in the second center region of the spoke body each include flattened cross-sections substantially accommodated in a longitudinal plane. In the second center region the spoke body is configured more asymmetric than in the first center region.

A device for removing burrs from a back cavity of a wheel includes a lower lifting synchronous movement arrangement, an outer ring brush arrangement, an inner ring brush arrangement, a synchronous movement arrangement and an upper lifting drive arrangement. When the device is used, an upper cylinder drives four clamping blocks to clamp the wheel synchronously through an upper guide rail, an upper gear and upper racks; an upper cylinder drives the wheel to rise and separate from a roller bed through upper guide pillars and upper guide sleeves; an upper servo motor drives the clamped wheel to rotate through an upper rotating ring. The present invention can be used for not only polishing the burrs at the back cavity of the wheel, but also accurately adjusting the position of each brush according to the flange size and the back cavity diameter of the wheel.

In one aspect, a method for forging a vehicle wheel with three-dimensional features may include steps of utilizing toe-clamps and center collets to reduce chatter marks and the effects of vibrations and harmonics; employing a parametric CNC program which allows for feed rates and spindle RPM speeds that are specific to the process of the vehicle wheel design; utilizing end-mills, bull-nose end-mills, ball-mills, chamfer tools, V-tools, custom rivet tools, and other commonly used CNC milling tools to machine the sides of the spokes on the wheels; utilizing a coolant to operate the CNC machine; providing a tool to make the three-dimensional features on the wheel; cleaning the wheel to remove coolant and debris remaining on the wheel; and painting selected areas of the wheel.
