Park Tool DT-2C Rotor Truing Fork Specially designed and precisely manufactured to gently adjust bent or damaged brake rotors. Each DT-2 features two different slot depths laser cut from high quality steel. Centered handle is vinyl dipped for comfort. The DT-2 Rotor Truing Fork quickly became one of my favorites. It’s a simple bar stock, with two different slots offering distinct leverage ratios to true rotors, meaning I don’t have to do it barehanded with my thumbs against fingers for leverage. That method works, but the DT-2 keeps oil off the rotors and allows a bit more fine-tuning than the aforementioned digital manipulation.
