This replacement derailleur hanger 283 is CNC machined from 6061 aluminum in our Colorado shop to exacting tolerances. Designed for Specialized 135mm SCS system compatible frames when using a SCS 135mm road disc hub, it features a 2.5mm offset for proper derailleur alignment, a black anodized finish, and includes two M3x8 flat head screws. Replaces Specialized part #S142600001. Note: do not confuse with Derailleur Hanger 146, which is for Specialized non-SCS frames.
