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.

Much better than previous model.
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.

Pricey but easy to use
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.

Very good tool to have
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.

Cycling.
Good quality. Ideal for fixing bent rear derailleur. A must have for a workshop. Recommended.

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.
