TREK (Rim) Brake Direct-Mount Derailleur Hanger - TRK-QR1

This is a Sigeyi precision-CNC aluminum derailleur hanger for Trek rim-brake / quick-release frames. Machined from a single billet of 7075-T6 aluminum for higher stiffness and impact tolerance than OE stamped replacements, to within 0.02mm of frame spec so the rear derailleur indexes cleanly. The hanger is frame-model-specific — it only fits the frame family it's named for.

Sigeyi code: TRK-QR1. Finish: Pink.
