- 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 being compatible with 16" to 29"+ wheels, whilst rotating out of the way to clear seat stays, racks, and other obstacles, allowing 360 degree measurement
- The long, precision-extruded aluminium body is built to exacting tolerances and provides ample leverage for making adjustments
- Thanks to the low-profile head, it fits low clearance thru-axle derailleur hangers and Shimano® Direct Mount hangers
- Made in the USA and covered by Park Tool's legendary limited lifetime warranty
