Park Tool Wag-4 Professional Wheel Alignment Gauge

Easy to use

Works as advertised. I had no problems using this and right away it showed me how bad my first wheel build was. That said, it seems a little overpriced for what it is.

Works....not outstanding...find something cheaper if you can.

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

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 tool has all the adjustments you need to fit a multiple selection of wheel sizes. Compares to the tools I have used in the many bike shops I have worked in all over the world. The best factor is the lightness.

Simple, easy and effective dishing tool. Sturdy and can be used with the tire on or off. Three adjustment points and delivered with instructions.

Used it on my neighbor and now Im in jail

I am glad I bought this. I do not know if another dishing tool would have worked or if a makeshift one would have been fine, but this tool definitely does what it says. I felt very professional testing the dishing on a recent rear wheel rebuild. So, this is a great tool for a beginner like me. My only complaint is that I find adjustment to be somewhat difficult and imprecise. The screw-on gauge makes it hard to make fine adjustments.

As a first time wheel builder this tool made correcting the dishing extremely easy. I had a one armed truing stand and without this tool, dishing would have been much much harder.
