By identifying the exact location and magnitude of any bend, you can make precise adjustments, restoring optimal performance and extending the life of your braking components.
The DT-3 is engineered to work seamlessly within a professional workshop environment. Accurately gauge the straightness of disc brake rotors while the wheel is mounted in a TS-2.2, TS-2, TS-4.2, or TS-4 Professional Wheel Truing Stand. The DT-3 features an infinitely adjustable, finely threaded indicator gauge. Works with any diameter brake rotor. This direct-mount capability creates a stable and repeatable measuring platform, allowing you to confidently identify even the most subtle imperfections that cause brake rub and pulsation.
Built with shop-grade durability, the DT-3 is a testament to Park Tool´s commitment to quality. The core of the tool is its precision-machined, finely threaded indicator, which allows for micro-adjustments as you bring the gauge closer to the rotor surface. This level of control is essential for pinpointing high and low spots with absolute certainty. The indicator tip is made from a non-marring material, ensuring that you can perform diagnostics without any risk of scratching or damaging the braking surface of your valuable rotors. This thoughtful design detail protects your investment while you work.
The versatility of the DT-3 makes it an indispensable tool for any modern bicycle mechanic. Its clever design allows it to work with rotors of any size, from smaller road and gravel diameters to the large 203mm and 220mm rotors found on enduro and downhill mountain bikes. Whether you are servicing a road bike, mountain bike, e-bike, or commuter, the DT-3 provides the universal compatibility you need. By adding this tool to your Park Tool Truing Stand, you transform your wheel service station into a complete hub, wheel, and brake rotor diagnostic center.
