A misaligned hanger causes skipping, missed shifts and wreaks havoc on the whole drivetrain.\u003c\/p\u003e\n\u003cp\u003eThe gauge threads onto the hanger in place of the rear derailleur and uses the wheel rim as a reference: the indicator is set against the rim at one point and compared at the opposite position, so the measured gap shows how far the hanger is out of line. It adjusts for 16\" to 29\"+ wheels and fits most frame\/hanger combinations, including low-clearance thru-axle hangers.\u003c\/p\u003e\n\u003ch2\u003eHow to align a derailleur hanger with the DAG-2.2\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMount the bike in a repair stand with the wheels level and check that the rear wheel is properly seated in the frame.\u003c\/li\u003e\n\u003cli\u003eRemove the rear derailleur and thread the gauge onto the hanger; if the threads are damaged, chase them first with the Park Tool TAP-10.\u003c\/li\u003e\n\u003cli\u003eSet the indicator against the rim at 3 o'clock, then rotate gauge and valve to 9 o'clock: with a gap under 3 mm the hanger is horizontally aligned.\u003c\/li\u003e\n\u003cli\u003eIf the gap exceeds 3 mm, bend the hanger by half the gap, in small increments, rechecking both sides.\u003c\/li\u003e\n\u003cli\u003eRepeat the vertical check between 6 and 12 o'clock: the hanger is aligned when three points 90° apart are all within 3 mm.\u003c\/li\u003e\n\u003cli\u003eIf fenders, racks or stays block the indicator, use the O-rings as markers and slide the indicator back to clear the obstacle.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose Park Tool DAG-2.2\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with virtually all derailleur-equipped bicycles\u003c\/li\u003e\n\u003cli\u003eAdjustable for 16\" to 29\"+ wheels (ISO\/ETRTO rims 317 to 630+)\u003c\/li\u003e\n\u003cli\u003eAlso fits low-clearance thru-axle hangers\u003c\/li\u003e\n\u003cli\u003e405 mm workshop tool for repeatable measurements on every bike\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAfter alignment always recheck the limit screws and derailleur indexing; a hanger bent several times that fails during correction must be replaced.
