Diagnose and repair bent or misaligned derailleur hangers with Park's DAG-3 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.

    • Replaceable M10 threaded tip
    • Fits low-clearance thru-axle derailleur hangers and Shimano® Direct Mount hangers
    • Length: 420 mm (16.5")
