This replacement derailleur hanger 146 is CNC machined from 6061 aluminum in our Colorado shop to exacting tolerances. It features a black anodized finish, attaches with two M3x8 flat head screws, and replaces Specialized parts #9890-4226 and #9890-4224. For Specialized non-SCS frames only — do not confuse with Derailleur Hanger 283, which is for Specialized SCS disc road frames.
