    PARK TOOL - DAG-3 - DERAILLEUR HANGER ALIGNMENT GAUGE

    An alignment gauge is essential for diagnosing and repairing bent or misaligned derailleur hangers, often the source of shifting problems. The DAG-3 features an all-new design, engineered and built to be light, accurate and versatile. The sliding indicator can measure derailleur hanger alignment against bicycle rims of any size, and rotates out of the way to clear seat stays, racks, and other obstacles, allowing 360 degree measurement. The long, precision-extruded aluminum body is built to exacting tolerances and provides ample leverage for making adjustments.

     

    • Compatible with 16" to 29"+ wheels (ISO/ETRTO rim sizes from 317 to 630+)
    • Replaceable M10 threaded tip
    • Low-profile head fits low clearance thru-axle derailleur hangers and Shimano® Direct Mount hangers
    • Length: 16.5” (420mm)
    • Weight: 22.75 oz. (645g)

    Awesome

    Don’t buy the cheap ones like I did first. This is so easy to use and solid. The cheap one wouldn’t fit on some bikes with short hangers so I got this and loving it.

    Best tool for the job

    I have the older version and this one is so much more convenient to use. It's not the cheapest but it's a worthwhile investment for years of use, even for a home mechanic.
