Park Tool DAG-3 Straightening Tool Derailleur Hanger

Park Tool DAG-3 Alignment Tool Derailleur Hanger

A alignment gauge is essential to diagnose and repair bent or misaligned derailleur hangers, which are often the cause of gear shifting problems. The DAG-3 has a completely new design that is lightweight, accurate and versatile. The sliding indicator can measure the alignment of the derailleur hanger on bike rims of any size and can be rotated out of the way to avoid seat stays, luggage racks and other obstacles, so that a 360-degree measurement is possible. The long, precisely machined aluminum body is manufactured with exact tolerances and offers great leverage for adjustments.
