Park Tool DT-2 Rotor Truing Fork
A rubbing disc brake is the most common e-bike annoyance, and a slightly bent rotor is the usual cause after the bike has been leaned on a rack or dropped. The DT-2 is a slotted steel fork that grips the rotor so you can bend it back a hair at a time while spinning the wheel and sighting through the caliper. It is a simple tool that replaces the adjustable wrench people use and regret. Clean hands and a clean tool matter — any oil transferred to the rotor will contaminate the pads. Heavy e-bike rotors are thicker than road rotors and take a bit more force.
Best for: Fixing brake rub from a bent rotor · E-bikes transported on car racks · Home mechanics with disc brakes
