PARK TOOL - WAG-4 - WHEEL ALIGNMENT GAUGE
For a wheel to perform properly, it is important for the rim to be centred between the locknuts of the hub, or “dished”. To check this, and to make precision adjustments, a wheel alignment gauge (also called a “dishing tool”) is a must. The WAG-4 allows easy checking of the dish on road, mountain, or BMX wheels from 16” to 29”. It works with any hub width and its innovative design even allows it to be accurately used with the tyre still on the wheel.
