Park Tool DT-2 Rotor Truing Fork

The Park Tool DT-2 Rotor Truing Fork is a solid, heavy duty piece of hardware. Sure it’s a simple idea for a tool, but it’s well thought out & designed. The tool is cut from a thick piece of steel (0.25 inches [6.25mm]), much thicker than those that are priced for less. The balance point on the DT-2 is pretty d@mn close to the midpoint of the tool. Once you hold Park Tool’s truing fork, you’ll immediately understand the price difference. The thickness of the tool & tapered middle allows for a comfortable grip & placement of your thumb like you would when using a knife to whittle or do a push cut. This allows for a good deal of leverage. The plastic rubber wrap around the DT-2 also adds to the comfort & handling of the tool while using.If your bike has disc brakes & you perform basic maintenance on it yourself, the DT-2 is something you should have in your toolkit. Sure you can use a screwdriver, pliers, channel-locks, almost anything that you can wedge & use as a lever, but w/the right tool for the job, you won’t mar, scratch or damage things unnecessarily. If you run larger rotors (180mm+), then you really should have this in your kit. This tool will pay for itself many times over. Besides saving the cost of paying the shop to straighten or replace a bent rotor, you’ll be able to keep your rotors true to prevent unnecessary & excess wear on brake pads which would result more frequent replacement.On some of the tools I have purchased for my bike kit, I chose to go w/less expensive manufacturers other than Park Tool. I don’t have money to through away. However, there are some tools I feel are worth the extra money, either because of the impact on safety, frequency of use (longevity of tool) &/or possible damage to bike while using. The A rotor truing fork is one tool I feel meets all those requirements.Even if you decide the Park Tool DT-2 Rotor Truing Fork is not for you because of cost, I would recommend you pickup another truing fork to maintain your rotors.Thank you for taking the time to read my review, I hope you found it helpful.

While I am still out on the advantages of disc brakes over good old rim brakes, I am riding a disc bike and stuck with the system. I have plenty of rim brake bikes (which are disc brakes if one wanted to push the definition) and find their maintenance to be much easier than disc brakes. While the stopping power of disc brakes is touted as an advantage, I am not so sure about that either. But I digress, as usual.I put off purchasing a disc tool like the Park model just because I’m a tightwad (and a lowly paid pseudoscientist), and figured an adjustable wrench would do fine. Yes, you can use an adjustable wrench to tweak the alignment of a rotor, but it is not very efficient, especially when the wrench loosens or tightens in between rotor adjustments. This tool does it much more efficiently, saving time and patience. There is definitely a learning curve to it, but that is most likely because I was afraid of putting too much pressure on the rotor. Small changes are probably best so you don’t damage anything.In sum, it is a great tool. The usual Park Tool fit and appearance is spot on and it does its job.Recommend

Good, quality product for rotor trueing. It is a one time purchase that will last essentially for the rest of your life. You might as well buy this once and be done, instead of buying a cheaper one that you’ll have to replace at some point in the future.

Well designed. Works great

I love my Park Tools, but you pay a premium for that Park blue color. This tool works well for straightening rotors. I was able to use this to “massage” a rotor back into being true. The two different slots allow you to provide different levels of force to the rotor depending on how out of true it is. It paid for itself in that one use. I will get lots of years of use of it.

I purchased this rotor truing fork for use on my MTB, but it can obviously be used on any type of bicycle brake rotor. I've used it a few times already in the short time that I've had it. Great tool, decent price. I would definitely recommend this tool.

As a hobbyist bike mechanic I source my tools from a wide variety of stores and manufacturers- Amazon to Home Depot to Harbor Freight. I only own a handful of carefully chosen Park Tools, but the ones I do own are worth their weight in gold. They are always the right tool for the job, and turn what could be frustrating hours with another tool or makeshift solution into minutes of enjoyable maintenance. The DT-2 is exactly that kind of tool. Flip your MTB upside down, spin each wheel slowly, and apply the wrench gently where needed to correct sections of untrue brake rotor. The angles of the rotor slots, width of the tools profile against the rotor, length of the lever, and the heft of the tool itself allow you to pry the rotor correctly with an even light force. You may not need to true your rotors very often, but when you do, this makes the job a five minute or less task. Great addition to my toolbox.

Yeah, you can buy a new rotor for anywhere between $20 and $50, but this thing has already paid for itself, and was super easy to use. GCN has a nice tutorial on how to do it and I was able to fix my rotors on the first try. I'm a heavier rider, and my disc rotors were going out of true all the time. It took maybe 5 minutes for me to true them up, and now they don't rub at all. Seriously, for under $20 this is a no brainer to have on your work bench for any at home mechanic. I was probably a little more gentle at first than I needed to be, but once you get over that hurdle and realize you can push a little harder than you think, it goes great...I mean, you could go to far with it, but just start gentle and work your way up from there.
