Park Tool Wag-4 Professional Wheel Alignment Gauge

If you want to take care of all aspects of your bike maintenance then this is a great buy

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

As a first time wheel builder this tool made correcting the dishing extremely easy. I had a one armed truing stand and without this tool, dishing would have been much much harder.

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.

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.

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

Bought the portable version. Hated it. It would flex. Spent the extra money on this one because it doesn’t flex. With the new hub designs, the old style triangle piece doesn’t work so this slider bar is the way to go

Easy to use, fast check of rim to hub alignment. Makes wheel building easier!

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!

My bike came with a bunk wheel that needed to be trued a lot. this tool was the missing piece I needed for my collection. once this was put on the truing process and future needs to true was reduced. I would buy the truing stand first and this one if you have to true alot. the parktool stand (i have the basic level -for now) is one of my favorite tools, and this tool compliments nicely
