PARK TOOL WAG-5 WHEEL ALIGNMENT GAUGE
For a wheel to perform properly, it is important for the rim to be centered between the locknuts of the hub, or “dished.” The WAG-5 accurately gauges dish on 24 x 1-38" to 29" wheels (ETRTO or ISO sizing of 571 to 630). Disassembles quickly for storage or travel and works with all hub types.
