“Impressive. Beautifully crafted with exceptional workmanship. The retracting alignment gauge retracts and redeploys its setting perfectly. Greatly facilitating it use. Thank you Park Tool.”

“I modified my old DAG-1 to work with newer dropout arrangements and it worked ok, and I am sure the DAG-2 would work just as well, but the rotating indicator on the DAG-3 is a big step forward for me to accurately align hangers. 360 degrees is where you want to be for a professional adjustment.”

“Takes the guessing out of whether or not the problem is the derailleur or the hanger. Well made easy to use, and helps straighten slightly off hangers with ease.”

“Fantastic tool, but the grooves on the pointer arm (the part that touches the rim) are a little difficult to see. No worries, grab a sharpie and mark every 5 big notches. *Now* this is the best tool I've ever used.”

“This derailleur hanger tool is worth the extra money hands down if you’re on the fence about purchasing it. It’s very well made and super fluid in its movements to get your hanger squared away to get you back on the trail again.”
