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.

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

My grandson is very tough on bicycles, always doing wheelies and this purchase was well worth it. The product is made very well and I believe will hold up even better than the original ones on a $400 bike.

Did not fit a prevelo alpha bike.

Works well with the right derailleur. Measure carefully.

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.

Works 100%!
