Patte de dérailleur Sigeyi Giant TCR à montage direct - GNT-QR1

This is a Sigeyi precision-CNC aluminum derailleur hanger for Giant TCR disc-brake frames. Sigeyi hangers are machined on a single billet of 7075-T6 aluminum — stiffer and more impact-tolerant than stamped OE replacements, and dimensioned to within 0.02mm of spec so the rear derailleur indexes cleanly and the B-gap stays right. The hanger is frame-model-specific — it only fits the frame family it's named for.

Sigeyi code: GNT-QR1.
