Park Tool Wag-4 Professional Wheel Alignment Gauge

Works great and very necessary for a full wheel check.

I found it easy to use and a good check on the wheel build accuracy. I checked a wheel that was just rebuilt at a local bike shop and found that while the wheel was true, it was a little dished...for those of you used to science terminology, the wheel alignment gauge could be said to check accuracy - how close to the true center mark you have centered the wheel rim. The truing stand (which I really like, by the way) could be said to check the precision - the deviation from the measured center. The analogy may not hold precisely, but it is the closest I can come to a short description of what these tools do. In any case, a good tool.

This performs as advertised. That being said, it feels cheap and is not up to the standard I expect from Park. But it does work, so Im keeping it.

adjusting it is easy, using it is easy, build quality is very good, its light, its blue Not a complicated device but this is a well thought out version and I wouldnt build a wheel without it

Bought the portable version. Hated it. It would flex. Spent the extra money on this one because it doesn’t flex. With the new hub designs, the old style triangle piece doesn’t work so this slider bar is the way to go

If you want to take care of all aspects of your bike maintenance then this is a great buy

When you pay for getting racing wheels trued you might expect them to be dished correctly. I got this because I got a rear wheel back that was way off to the left. It turns out that most of my wheels are not correctly dished, because this tool doesnt lie. Now I have the fun of re-dishing most of my wheels, but at least this will help me ensure they are perfectly aligned. It is adjustable for several wheel sizes, and can be used without removing the tires.

Works great for checking or setting dish of wheel even with tire mounted.

Works great, accurate! Only issue is the item is used not new in the package. Item has some cosmetic damage like its been banged around but nothing that affects its accuracy or use.

Could be made a little better. depth gauge is jerky to use. Looks cheap. Works. Not much else to say.
