Park Tool DAG-3 - Derailleur Hanger Alignment Gauge, Black

Not cheap but worth it 100%. So much better than the previous model which wouldn't help at all when it came to rotating the gage. Perfect for the job..... Usual Park Tool excellence.

Strong material easy to use wish I had it earlier great price and a piece of kit

The best hanger tool I’ve owned, easy to use and extremely well made, this derailleur alignment tool just does what it needs to do.

lovely build quality and joy to use. Gone are the frustraing days of trying to sort out my gear indexing ;)

A high quality tool that makes derailleur hanger alignment a pleasure. The tool is clearly well made with the well finished aluminium head and shaft made as a single piece. The round shaft has a groove along it's length that keeps the sliding pointer aligned as you move it in use. The pointer also swivels to allow clearance of the seat and chainstays of the frame as you move from one side if the wheel to the other. All this makes it very quick and convenient to use. Clearly some thought has gone into the design making it much better than cheaper versions of this type of tool. Recommended.

I wasn't sure about getting this as it's an expensive tool for something that you don't always need to use, but glad I got it as I have a bike that wasn't shifting 100% in 2 of the gears, so I bought (one by one) a new derailleur, new chain, new premium cables, and a new shifter. Turns out the derailleur hanger was off now it's 100%. It's a good tool to keep hold of for future adjustments, fixing other people's bikes and apparently a lot of the new derailleur hangers aren't 100% straight either.

High quality tool which is easy to use. Only slight flaw is there is a tiny bit of play but it is possible to allow for that when carrying out the checks. Packs away quickly with no faffing about which is a bonus.

So easy to use and very accurate.

Perfetto

I've only used this on two bikes, but honestly, it was still worth it for me. It gave new life to two bicycles I would've written off, and gave me the encouragement to completely rebuild one of the bikes into a completely different animal. Very easy to use, especially with the latest quality of life enhancements to the product.

Excellent as usual with Parktool tools. Can't go wrong with this tool. There are many out there that are very good. Its just that this tool looks and feels different and works better than the rest including the older Parktool version. But not very pleased with this seller. Will not buy from this seller anything anymore.

Amazing and well built! It’s what you would expect from park tool

Wie nicht anders zu erwarten eine Wahnsinns Park Tool Qualität. Absolutes Must Have in der Fahrradwerkstatt.
