For a wheel to perform properly, it is important for the rim to be centered 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. An accurate and truly versatile wheel alignment gauge that belongs along side every truing stand.

Rated 5 out of 5 by Stella Easy to use, precise, and sturdy
I've worked with this tool in a bike shop and, now that I'm planning to build wheels to sell, I've purchased the WAG 4. I could have gone for the WAG 3, but since I also true the wheels of the bikes I'm riding, this is definitely the better choice as I don't have to take the tyres off.
Another good thing about this one is that it fits perfectly into the Park Tool jig, so you don't need to remove the wheel to check the dishing.

This makes dishing the real wheel so much easier. Of course, you can guess the dish by trial and error in the bike frame - but using this tool is the best way to make sure it is accurate. Very useful to have if you like to build your own wheels. Be warned also that some bike shops who build wheels may not even bother to check the rear wheel dish (this does happen!). It IS important to get it right.

Rated 5 out of 5 by Anonymous Need to true a wheel then you need a trueing stand & a tension meter and THIS. It is dead simple to use, the enclosed instructions make it really easy to understand. Many people (inc shop mechanics) think trueing is all you need to do, they are ALL wrong. Dishing the wheel is so important. It is simple it sits on the trued rim, the centre guage tells you how far out of centre the hub is. You adjust - re true - check again till it is right. Here is the best tip - LOOSTEN ALL SPOKES even if just replacing a single broken one. Then true / dish checking the tension as you go. At EACH stage stress the spokes (squeeze them hard in pairs). Your done when the spokes are @ the top end of the stress guide (park tool tension meter). The difference to your ride is AMAZING and the satisfaction is doing it makes it all worth while...HONEST!

If there're some marking with metric scale graduation on the measuring blade is more perfect.
