The Hennessy Coats 1600-3D Wheel Balancer is designed to deliver a one-spin performance balance every time. The motor and spindle are combined into a pre-balanced assembly that always stays calibrated to zero. The Probalance technology minimizes static and unbalance, while the touchscreen system interface is built to last and can be used while wearing gloves. The Speed Thread addition provides the ability to thread the hub nut with the push of a pedal.
