Park Tool Wag-4 Professional Wheel Alignment Gauge

Gift to my son and he is enjoying it. He uses almost every week to fix his and his friends bikes

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

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.

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.

Meh. Its fine. Not like the old skool Hozan, but its priced fairly at the wholesale level.

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.

Perfect tool for keeping wheel straight

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).

Not sure how you would align a bike wheel without this tool

It works OK, it is too simple not to! The biggest drawback is the depth gauge locking handle. After you put the feeler gauge close to the wheel axle you turn the knob to hold the gauge in place. As you tighten the knob the gauge actually moves, what a poor design, especially from Park Tool!! You flip the wheel over and check the other axle but arent getting a very accurate reading since the feeler gauge moved when you tightened the know. A screw type measuring feeler gauge would be much better, especially if it would give a measurement in millimeters.
