ParkTool DAG3 Aimer Set For. Derailleur - Black

An alignment gauge is essential for diagnosing and repairing bent or misaligned derailleur hangers, which are often the cause of shifting problems.
The DAG-3 features an all-new design, designed and built to be light, accurate and versatile.
The slide indicator can measure the alignment of the derailleur hangers relative to any size bike rim, and pivots out of the way to clear chainstays, racks and other obstructions, allowing 360-degree measurement.
The long, precision-extruded aluminum housing 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 backlash derailleur hangers and Shimano® Direct Mount hangers
