Park Tool Portable Wheel Dishing Gauge - WAG-5
The Park Tool WAG-5 Dish Tool accurately checks the dish, or offset, on all 26", 27", and 700C wheels. Measurements are taken comparing one side of the wheel to the other to determine if the rim is in the center of the hub. The Wag-5 easily folds in half and fits into most tool boxes. It's perfect for the race or home mechanic.
