Park Tool Wheel Alignment Gauge
For wheels to perform properly, it's important that the rims be centered over the hubs. To check this, and to make precision adjustments, Park's Wheel Alignment Gauge (also called a dishing tool) is a must. It allows you to easily check centering on road, mountain and BMX wheels from 16 to 29 inches in diameter. It works with any hub width and its innovative design even allows it to be accurately used with the tire still on the wheel. The Wheel Alignment Gauge is a necessity for every wheelbuilder.
