Park Tool DAG-3 Derailleur 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)

DAG-3, 3rd time's the charm
"The original DAG tool has an interference problem with the hanger on modern mountain bikes. DAG-3 solves this and is much more robust and accurate. The play at the pivot point is much reduced giving accuracy of about 1mm at the rim. The rotating measuring arms are genius. Expensive but worth it - poor shifting on 12 speeds RD is often a hanger alignment problem."
