Proper alignment of a bike's derailleur hanger is important for reliable shifting. While a derailleur hanger can be bent when a bike is crashed or dropped on
its side, even new frames often have misaligned hangers. The Park Tool DAG-2.2 provides a simple, accurate means for checking hanger alignment and for
straightening hangers that are not properly aligned.
ASSEMBLY
Install indicator (Ref #4) into sliding bracket (Ref #7) and tighten
knob (Ref #1). Install one o-ring at each end of indicator. The
o-rings will serve to retain indicator in the DAG-2.2.
INSTRUCTIONS
1. Install wheel in frame. Make sure rim is correctly centered in frame.
2. Remove derailleur from derailleur hanger.
3. Thread inside shaft (Ref #3) into derailleur mounting hole.
4. Loosen knob and move sliding bracket and indicator so tip of indicator
contacts outside edge of rim (position A). Tighten knob.
5. Move sliding bracket so indicator is clear of rim. Then rotate tool 180
degrees to position C.
6. Move sliding bracket and indicator to outside edge of rim. If tip of indicator
is within 4mm of outside edge of rim, the hanger is aligned horizontally. If tip
of indicator is 4mm or more away from rim, or if indicator presses against
rim, the hanger is misaligned. Move sliding bracket and indicator so they
are clear of rim. Then use weldment (Ref #6) as a lever to bend hanger into
alignment horizontally. Repeat checking and bending between positions A and C until
clearance is less than 4mm.
7. After achieving correct horizontal alignment, keep indicator in same position and rotate
to position B. If clearance between outer edge of rim and tip of indicator is less than 4mm,
rotate tool to position D. If clearance is greater than 4mm, or if indicator presses against rim
at position B or D, use weldment as a lever to align hanger vertically.
8. With properly aligned hanger, tip of indicator should just contact outer edge of rim at one
position and have no more than 4mm clearance at any of the other positions. Check and
align all four positions until this is accomplished.
NOTES:
The two O-rings on the gauge bar may be used as markers when using the DAG-2.2 on a bike with interference from a rack or other accessory. After moving
indicator to rim and tightening knob, move outer O-ring against sliding bracket. When it's necessary to clear a rack or other accessory, simply loosen knob, pull
indicator back to clear rack or other accessory, push indicator in until O-ring contacts sliding bracket in original position, and tighten knob.

Always take
readings with
indicator at valve
hole to insure
wheel trueness
will not impact
accuracy of tool. Also, always take readings at outside
edge of rim to minimize errors that may be caused by
rim's sidewall slope.
