Park Tool Wag-4 Professional Wheel Alignment Gauge

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

fare enough, easy to work with actually so simple and reliable, so light not solid metal but hullos, enjoy your time ;0)

Beautiful Park Tool great quality.

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

accuracy

it was easy for me to see if my wheels where aligned. makes it easy to see if adjustment is necessary.

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).

This has aided me in my quest to learn to build wheels and continue to enjoy the whole cycling experience; riding and maintenance.

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

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.
