The Park Tool Rotor Truing Fork helps get a disc brake back to its original shape. Disc brakes can warp after a lot of use or overheating and cause pad rub. This tool is laser cut to guide the brake rotor back to a perfectly straight shape. The fork has two different slot depths and is made of high grade steel with a comfortable vinyl handle at the center. The Park Tool DT-2 Rotor Truing fork is a great way to make sure your ride is as efficient as possible.
