Having a mountain bike with disc brakes is fun but can be difficult to maintain. Trying to identify the dings and bends with the naked eye can be frustrating. I mounted this on my stand and was able to find the trouble areas in moment. Park Tools never disappoint.

My cheap wheel truing stand (Pyramid Deluxe Wheel Truing Stand) didn't have a mounting point for this rotor truing stand, so I clamped it to my drill press, and drilled a hole in it. Mounted perfectly.

The quick-release is nice, because it allows you to quickly swing it out of the way if you're working on a wheel, and not a rotor at the moment.

I've already trued several rotors with it a couple that I didn't even know where out of true. If you have a bike with disc brakes, and you already have a wheel truing stand, this tool is a must-have. You must have a wheel-truing stand in order to use this tool, though or else you won't have anything to mount it to.

Good attachment if you have rotors on your bike wheels. You can get away without it and setup your own, but it does the trick and isn't all that expensive. Satisfied with it.

Honest reviews on Park Tool Rotor Truing Gauge - DT-3

I was a professional bicycle mechanic for about a decade and used a lot of Park tools over the years. Their truing stands were great for truing wheels and this is a great attachment for truing brake rotors.

I considered a tool with a read-out gauge, but the precision of the gauge will likely only frustrate everyone but the most precise mechanic--I wouldn't even recommend a gauge for shop use if you want to be productive. I'd rather spend time riding as opposed to working on my bike so this will keep me from obsessing too much about my rotors.
