This is a wheel truing stand for bicycles purchased from AliExpress. I mainly used it for wheels with disc brakes, but I think it can also be used for rim brake wheels. It's sturdy, so the accuracy should be decent. It has dial gauges to check for vertical and lateral runout. The tips of the dial gauges have been replaced with roller-type tips to prevent damage to the rim (they were originally rod-shaped). Please be aware that this is a used item, so there may be some minor dirt and scratches.
