An updated version of the popular DAG-1, the new Park Tool DAG-2 Derailleur Hanger Alignment Gauge utilizes a longer measuring pointer, longer threaded stud and a longer, narrower alignment boss to fit a wider variety of bikes.
  • Solves a multitude of derailleur shifting problems, most notably with index shifting systems
  • Extremely steady in operation and simple to use
  • Threads directly into the derailleur hanger
  • Gauge bar holds a gauge which marks the distance to the wheel
  • Gauge then is rotated with the wheel to the 3, 6, 9, and 12 o'clock positions, noting any differences in measurements
  • Alignment of the derailleur hanger is accomplished by applying pressure to the tool's arm - the results can be checked instantly
  • Made with heavy gauge steel and chrome plated for long shop life
