A short review of the Park Pool dag-2.2 derailleur hanger alignment gauge.

I have owned this tool for a good year or so now, and whilst it could be considered very expensive at the purchase cost of about £55.00, I was lucky enough to share the cost with a friend.

This has quickly become one of my favourite workshop tools, and is now one that I would consider as being indispensable.

Riding off road and in the terrain that I do, it is an all too often occurrence that the rear derailleur is knocked or bent out of alignment. This tool has taken all guess work out of straightening the hanger, and is really easy to use.

If I were to have any gripe about it, then it would be that it wouldn't take much to damage the thread that inserts into the hanger, and that the rubber O ring design of the adjustment bar, could be improved.

I have now also had the chance to use the X Tools version, and at roughly half the cost depending upon where purchased, this makes a far better proposition, and in respect of the thread, is superior.

To end.... A superb tool, but the cheaper options are probably a better choice.
