Sigeyi Cannondale Direct-Mount Disc Derailleur Hanger - CND-TH1

The CND-TH1 is one of three Sigeyi derailleur hangers for Cannondale disc-brake frames — the TH1, TH2 and TH3 each fit a different Cannondale frame family, so match your frame model against Sigeyi's fitment chart before ordering; the code is the fitment. This is the direct-mount TH1, machined from 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.

Sigeyi code: CND-TH1.
