Rotor Truing Tool DT-2.2

Park Tool Rotor Truing Tool DT-2.2 is a purpose-built disc brake service tool designed to straighten bent bicycle disc brake rotors with controlled, repeatable adjustments. By bringing a rotor back into plane, it helps reduce brake rub, quiet noisy braking, and restore consistent lever feel without removing the rotor from the bike.

• Precision rotor straightening - Gently corrects bent disc brake rotors up to 2.5mm for improved clearance and more consistent braking.
• Multi-slot interface - One long slot and two short slots increase contact options for secure engagement on a wide range of rotor designs.
• Broad rotor compatibility - Slot variety improves fit across different rotor thicknesses and cutout patterns, reducing the chance of slipping during adjustment.
• Disc brake maintenance efficiency - Speeds up rotor alignment during tune-ups and wheel swaps, helping keep modern disc brake bikes running quietly and cleanly.
