Like many, I’d rather not shell out a ton of cash for a tool that will likely get very little use. I had a lightly bent hanger on a mountain bike. The hanger itself was relatively new and hadn’t been wrecked so it was probably a manufacturing problem. It was worth at shot getting it straightened so i tried this tool out.
It worked really well. The threads are smooth and well machined for a the hanger so attaching it was easy.
The only issue, and thus 4 stars, was that not all of the pieces fit together tightly. The “bar” or whatever one would call the longer piece, was a little loose fitting around the “fixing bolt”. I’m not really sure what to call the specific pieces but it was remediable but holding it in place while measure the distance of the sliding pin from the rim.
All in all, a good value for a tool I probably won’t need very often.

Nicely made and good value for a home shop. Strong enough to adjust most drllr hangars.

This alignment tool is all metal and feels both robust and precise. The directions are clear and concise on how to assemble the tool and it is extremely easy to use. I think this is an attractive alternative to expensive professional level solutions from Park and others. This worked perfect but in my case the hanger was fine and the derailleur is just worn out so needs replaced. Even though this is specialized it is a very helpful tool if you do your own bicycle maintenance. Recommended!

This Derailleur Hanger Alignment tool is great. If you work on your mtb or road bike at home this can help with a lot of alignment issues. The tool feels very solid and well made in design. I will be saving a trip to the bike shop with this for sure. I tried it out this week after changing out my cables on my Kona mtb and it does help quite a bit to have the alignment adjusted properly. For this price its well worth adding to your garage bike tools.

This derailleur hanger alignment tool is of good quality and smooth operation. I like the round bar versus the square bar that other styles of derailleur alignment tools have. This allows you to set the measurement bar and then twist it to get past the seatstays and chainstays so that you keep the same measurement, especially since the gauge etched in the measurement bar is difficult to see. The square bar style forces you to move the measurement bar so you have to do more to keep track of values and placement. The attachment for measuring dropbar controls is a nice bonus too, but I had to add locktite to the threaded rod of the attachment, otherwise the rod stayed in the star nut when I went to remove it from the bike. There is a little play between the rod that screws into the derailleur and the rest of the tool, but I couldn’t say how it compares to a name-brand version of this tool and I don’t know how much of an impact it has on the alignment process. I was able to successfully align a slightly bent derailleur hanger on a bike that was having shifting issues after the user crashed and then the report from the user is that it’s now shifting even smoother than when they got the bike new and set up by a reputable bike shop. It’s a simple tool and there are very expensive versions, so it’s nice to find a good value on a tool that really doesn’t get used much – but when you need it, you need it.

Used this on my SL4 and my S-Works Venge. Great alignment tool for the rear hanger. Takes a some assembly and some time to figure out, but it is very effective. I also like that I was also able to use it to verify other dimensions on the bike. I was wanting to adjust the horns on the handlebars inward so they would be more ergonomic with my hand positioning while riding. I’ve always had issues making sure both horns were at the same height and distance. Having this alignment tool was a great help. I was able to easily measure one horn, and duplicate the opposite horn to the exact height. The distance was easy to determine using a measuring tape and a wooden dowel marked at the correct distance. Overall, it was far easier than what I had been doing in the past. The rear derailleur works great. Haven’t had any issues with it skipping, chattering or grinding. Overall, great tool. Also like the custom cut foam used to store it when not in use. In fact, I just placed it in my tool box for easy storage. Great Alignment Tool!

I’ve never used a real derailleur alignment tool before. I had made my own out of some angle iron and a bolt, and while it worked it was awkward to use. This is much nicer to use, although it does have one flaw.
Overall it’s pretty easy to figure out how to use this. One end threads into the hanger and the other end has a sliding bar that you use to compare the distance from the rim top and bottom and side to side. You can slide the gauge up and down the rod to match your rims. Everything works pretty well, but I do find that mine has some play where it screws into the hanger which means you can get a different distance depending on how you push on it. It’s still quite usable, but it’s something you have to keep in mind.
I’m generally happy with the tool and you’re much better having one of these than not. A bent derailleur hanger will play havoc with your shifting and one of these is the only way to really fix it.
