Sigeyi Colnago C64 V3RS Derailleur Hanger - Oil Slick

This is a Sigeyi precision-CNC aluminum derailleur hanger for Colnago (C64 / V3-Rs) 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.

Finish: Oil Slick.
