Abbey Bike Tools preHAG provides a fast way to check derailleur hanger alignment without removing the derailleur. Designed as a quick diagnostic companion to the Abbey H.A.G. Hanger Alignment Gauge, it allows mechanics to visually confirm whether a derailleur hanger may be bent and affecting shifting.
The tool presses onto the largest cassette cog, creating a reference plane that makes it easier to judge the alignment of the derailleur cage relative to the cassette. While not intended to replace a full alignment measurement with the H.A.G., the preHAG is useful for quick pre-ride checks, post-crash inspections, or fast workshop diagnostics.
