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.

It's a bit smoother to use than the older DAG-2.2. There is a bit of play in some of the moving parts which makes it a little tricky to get very precise alignment if you're that way Inclined, but that's not a big issue since there should be a few mm of tolerance with hangar alignment. Never the less it's a very well engineered tool.
