Perfect fit
I wasn’t 100 percent sure that this was the correct hanger, but it was a perfect match and a quality replacement part.

Perfect fit for DROP OUT Domane
I bought this quickly without looking too closely at the listing.. so it's my fault completely. This is the perfect derailleur for the older Domane with caliper brakes. If you are looking for a Domane derailleur hanger for the DISC model. This isn't it and that's ok I kept this as a backup since my wife has the older caliper brake model and it fits perfectly.

fits, came with funny bolts
seems like an adequate replacement (it fits), but the two bolts that came with it have different hex head sizes (though the thread size and pitch are the same)… weird, eh? time will tell if the material is good…

A direct replacement. Very nice.
Arrived very fast, i was surprised to learn it is aluminum and not steel. The supplied hex head screws in the bag are 2 threads shorter then what's in the bike's Shimano 105 hanger, so i used the original longer screws for more bite without sticking out on the inboard side. Now it shifts like it did the day i bought the bike, it shifts in way under 1 crank turn. Additionally, make a weighted plum string and hold it up behind the cassette and jockey wheels inline with the chain and jockey wheels and see right away what is running true and what part of your pulley wheel cage is bent inboard or outboard.
