      I wish I bought this tool years ago. Follow the instructions and you can't go wrong. Tool is well built and should be used on any bike with a rear derailer. Great price!

        In the long run this tool will save you more money and headache than any other tool you will buy. I can easily straighten all but the most mangled derailleur hangers. I actually use mine even when installing a new hanger just to make sure everything is aligned. A well build and designed tool.

            Park Tool has done it again. This tool is PERFECT for fixing those annoying shifting problems. You won't regret buying this tool. It sure beats having to buy and replace hangers all the time. This tool is easy to use and will straighten out your hanger every time.

            Super easy and intuitive to use.
            Don't forget to rotate the wheel with the tool to compensate for a possible untrue wheel.

            For Shimano Shadow Derailleurs (sorry but someone should come up with a better name for this thing!) you can also leave that fist chip on the hanger and adjust including that piece as this thing usually bends as well when you hit a rock and adjusting the hanger only will not help.
            All you need to do that is an additional 10mm washer.

                You don't use this tool often but it is the key to smoothest shifting. I checked out all the bikes in the household and even the newest frame was out of alignment. The tool is fast and easy to use and rigid enough to use as both alignment gauge and straightening tool.
                I love it!

                      This tool is essential for avid mountain bike riders that experience the occasional dent and ding of technical riding. It is quick to attach and align the hangar without removing the rear wheel and gets the bike back on the road quickly. It is a little on the pricey side for what it is but there is no other replacement that matches its quick and easy performance. Add it to the tool box and your friends will be sure to come to your garage at least once to use it.

                      Nearly all of my shifting problems over years have come back to a bent derailleur hanger. Hard to get right by eyeball. You'll save hours of frustration and (fewer bike shop dollars) by getting a DAG2

                          Had a bike mishap, crashed and bent up my derailleur. Could not shift in every gear smoothly afterwards. Derailleur didn't look bent? Got this tool and it worked great. Simple to use and did not take long to correct problem. Now I am able to shift fine, like a new bike! This is a must tool for the tool box!!!!
