2 Pcs Universal Bicycle Bike Derailleur Hanger Frame Gear Tail Hook, Silver Tone

The picture on the listing page that shows the dimensions for this AUTUT Derailleur Hanger contains an error! The threaded hole is NOT M9 as shown, which is a good thing, because the thteads on the hangers I received and those on the mounting/pivot bolts for just about every rear derailleur on the face of this earth are M10 x 1.0.The part fits perfectly, good thing it wasn't made to the erroneous "spec".I suspect some non-technical person eyeballed the ID of the threaded hole using a ruler and assumed it was an M9 thread since it does indeed look to be about 9mm diameter. The problem is the MINOR diameter of an M10 x 1.0 INTERNALLY threaded hole is about 9mm, but that doesn't make it an M9 thread. All is well in the reald world, just not the paper one.

I compared my stripped out threads MTB derailleur hanger bracket to the photo provided and it was a perfect match. The 2 ea. brackets arrived fast. You install one bracket and keep the other bracket for a spare.

was exact fit for hitroad safari with Shimano derailers my hanger broke

Replaced a broken bicycle derailleur hanger with one of these months ago. It was a perfect fit, and has worked well so far.

Not universal by any means. My townie elektra was one of those non-universal models.Pro-hindsight-tip: Check the hanger bolt dimension/location in hanger, not just the shape and size. ;)

Fit perfectly on my bike. I have a se bike. Om Duro 27.5 with a ten speed sram gx derailleur. And it fit perfectly.

Does not fit Trek Navigator 3.0 for many reasons and I *did* in fact match my hanger’s dimensions to the picture. The problem is they didn’t give the couple dimensions that *don’t* match in my case. I.e., too wide on top for inlay, two holes too close together (angle of hanger not quite right to space them apart, etc.).

This is a Derailleur 27, it fits the Ozark Trail Vibe perfectly.
