Park Tool Wag-4 Professional Wheel Alignment Gauge

I can use it with a tire still on the rim.

This iitem does what it is designed for. For long-term use, and not having to rely on a bike shop or mechanic, the price was reasonable.

Park tools. The best. Nothing more to say.

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

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.

Used it on my neighbor and now Im in jail

Not much to say here--the design has been refined over time, and it is state of the art. I like it just fine.

I love the tool over all, it helps me keep our family of 5 rolling. I took 2 stars because after truing and dishing over 20 wheels the first month, I found it to be fairly clunky with the adjustment knob. Its really hard to hold the tool and wheel and make the needed adjustment. A few times I had to set it down and come back in 10 minutes or so. I was trying to get 3 sets checked in an afternoon and it slowed things way down.

Easy enough. I had a wheel Ive been having problems with broken spokes - it was true but still had problems. Got the dishing tool and realized I was significantly out of whack. Corrected the dish and everything is great. There are other similar products that I dont have but this one was quite easy to use. Definitely recommend...

It fixed the problem definitive.
