The DAG-2.2 is an indispensable shop tool that can be used to both measure and straighten misaligned derailleur hangers solving a high percentage of shifting problems.

  1. Gauge bar made of heavy gauge, chrome plated steel
  2. Adjusts to fit 20″ to 29″+ wheels
  3. Replaceable threaded tip
  4. Upgraded large inner shaft for added strength*
  5. Tighter tolerances for improved accuracy*
  6. Improved clearance and reach to fit more frame/hanger combos including low clearance thru-axle derailleur hangers*
