Park Tool Wag-4 Professional Wheel Alignment Gauge

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.

Used it on my neighbor and now Im in jail

Plastic blocks wont scratch your rims. I like this feature. I used this on 29 in rims. I had no problems. It works well. It is very sturdy.

It does the job, but adjusting the gauge is annoying because it moves as you tighten the knob. It can only really be used with the wheel in the stand, because you need to grasp the gauge with as many fingers as possible (to hold it still) while you rotate the knob with whatever leftover fingers you have left. The WAG 3 is a much better design.

This is a great tool and the blocks allow keeping the tires on while checking wheel dish. Im not giving it 5 stars only because the instructions are not super clear as to which spokes need to be tightened when there is a gap at the hub. So of course I ended up increasing the gap that was already present by tightening the spokes on the wrong side.

Exactly what I needed. Thought i could get by with just the truing stand, but this is a must for precise dishing and truing.

If you know what this is the odds are you are getting it. Beside a hand built dishing tool this works like a champ. Make sure and store it correctly when not in use. I have some scrapes in the plastic from storage and being dropped that I have had to file down to make it true.

excellent

If you true/build wheels, this is a must have as I have built tens of sets over the years, but only 30% correctly. You need the right tools for the job as I am proof that anyone can build a wheel, but not everyone can build a wheel right.

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