Derailleur Hanger 200 – 6061 Aluminum, Trek/Gary Fisher W294666/W307718, M12x1.25

This replacement derailleur hanger 200 is CNC machined from 6061 aluminum in our Colorado shop to exacting tolerances. It features a black anodized finish and replaces Trek/Gary Fisher parts #W294666 and #W307718. Note: post is 16.5mm (0.650") in length with M12x1.25 thread — verify before ordering. Trek recommends applying removable thread-locker (e.g. Loctite 243) during reassembly to prevent the retaining nut from loosening.
