Direct-Mount Derailleur Hanger with Screw for Disc-Brake Road Bikes

This bike part is a rear derailleur hanger designed for disc-brake road bikes, providing a direct-mount connection at the frame dropout. It comes with a matching mounting screw, so the hanger and hardware are paired for installation. Built as a slim machined metal disc-brake derailleur hanger with circular mounting openings and a long oval center cutout for a compact adapter shape. The matte black surface gives the rear derailleur hanger a clean, understated look that blends well with modern bike hardware. As a derailleur hanger, it helps position the rear derailleur correctly on the bike and serves as a dedicated gear bracket interface for the drivetrain.
