Place the tool's arms on the rim on one side of the wheel and adjust the central gauge rod until it just touches the hub's locknut or axle end, then flip the wheel around and repeat on the other side without changing the rod's setting. If the rod touches evenly on both sides, the wheel is properly dished, and if there is a gap on one side, the spoke tension needs adjusting to recentre the rim.

This tool has a marked wheel-size scale covering everything from 16 inch wheels through to 700c, so it works across most children's bikes, folding bikes, mountain bikes and road bikes. The built-in size markings mean you do not need a separate tool for each wheel diameter you work on.

Even occasional truing benefits from checking dish, since fixing a wobble by adjusting spoke tension on only one side can accidentally pull the rim off-centre relative to the hub. Having this gauge on hand means you can true your wheel and confirm it is still correctly centred in the same session, rather than guessing.

Wheel building and truing does take some patience to learn, but a home mechanic with a truing stand, spoke wrench and this dishing gauge can absolutely true wheels and check dish at home with practice. It is a valuable tool to have if you build or maintain wheels for yourself or family regularly, since dish accuracy is something a shop would otherwise charge for as part of a wheel service.

This gauge uses an aluminium arm construction with an adjustable central gauge rod, giving a good balance of light weight and rigidity so the reading stays accurate and does not flex under normal handling. With reasonable care, it is a tool that will last through many wheel builds and truing sessions over the years.
