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.

It fixed the problem definitive.

If ever youre worried about your wheel dishing, this tool is for you! Wherever this supplier gets his tools from, I can review this product sold by him as totally awesome! Not to mention the product still retains the original paperwork instructing you, the buyer, of the tools assembly and use, not to mention the paperwork on the warranty offered by Park tool. I would buy from this supplier again for my wheel builds, as should you! Five stars, my friends!

I successfully and quickly aligned my wheel using this Park tool. After having broken and replaced a spoke and then truing the wheel and reinstalling, it was rubbing a brake pad, very out of alignment. Bought this. The Park tool is easy to use, is very accurate, Im glad I bought it. I tried buying a less expensive tool, but somehow Amazon shipped to the wrong location, then refunded my money. I then spent an extra $14 to buy this one and get quick delivery (Prime). I am very satisfied with this purchase and do not regret the extra $14. I own 5 bicycles and will be using the tool often.

Its a great tool if you are one of those who is obsessed with being precise. I good wheel truing stand will easily get you close enough though. As for quality; Park Tools never disappoint.

The first time I used this otherwise nicely-made tool it was apparent that the knob that secures the depth feeler was difficult to adjust just right so that the feeler didnt move when I secured it for depth. I added a stainless steel 10 mm I.D. washer between the knob and the feeler and that solved the problem (the washer fits exactly within the recess in which the feeler slides). I can now adjust the knob so that the feeler slides easily for depth, and then tighten the knob just a bit to hold the feeler without it moving off the depth setting. A 17 cent fix that I would recommend you try. P.S. (The manual doesnt mention that the slider blocks can be secured for width by slightly tightening the screws on the bottom).

If you build or true your own wheels, you really do need a dishing tool. Even if you have the very excellent Park Truing stand that automatically centers the rim, its still nice to have this tool for a quick check without having to put it on the truing stand.The adjustable ends allow it to be used without taking the tires off. Very easy to use and very accurate. Im completely pleased with my purchase.

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.

Its a little weird to use, but once you get used to it, its great. The older alignment tool was a little easier to setup. It had a more precise indicator. But, so far, the way Ive found to use this is to check that the blocks are hitting the rim, and not the tire. Push the center gauge part down into the concave part, and tap it over the axle of the wheel. Get it so that it clears the axle if you slide it back and forth over it. (Check for clearance) And then flip the wheel over and look at the back side. You should get a better reading doing it that way. Its a pretty awesome tool, and can save a lot of time and futzing with caliper adjustments. A must have for wheel builders.
