Overview

What is the Park Tool DT-2.2 Rotor Truing Tool built for?

The Park Tool DT-2.2 Rotor Truing Tool is built to straighten bent disc brake rotors, which is the fix when a wheel spins true but the brake still rubs. Rotors can bend from heavy use, excessive heat, or impact, and new rotors are not always perfectly straight. The DT-2.2 has one long slot and two short slots so it works with a range of rotor designs, on rotors up to 2.5 mm thick. Slide a slot over the high spot, apply a gentle bend, spin, and check again.

It is made from high quality steel with a vinyl dipped handle for comfort.

How do you true a disc brake rotor with the Park Tool DT-2.2?

To true a rotor with the Park Tool DT-2.2, spin the wheel and find the spot where the rotor touches the pad, slide the slot that fits over that section, and bend it gently away from the rub. Small corrections work best, so check again after each bend.

What rotors does the Park Tool DT-2.2 fit?

The Park Tool DT-2.2 fits disc rotors up to 2.5 mm thick, and its one long slot and two short slots are designed to work with a range of rotor designs.

Which slot on the Park Tool DT-2.2 should I use?

Park Tool says to use the long slot for narrower corrections and the short slot, engaged at the arm, for wider corrections. On two-piece rotors, bend only at the outer edge of the rotor, never at the arms.
