There was just a thread about proprietary parts--this is a good example--one of the carriers of derailleur hangers advertises they carry over 550 types--is this really necessary!? Seems like there could be at least an attempt at standardization--even if it got it down to 150, it would be an improvement.

I looked, honest I did. I could not find one on the interwebs.
It seems to be Jamis specific, I could find no generic.

whaoh- that Web link is in Japenese. I wonder if that's where it's manufactured?

When you find a supply, order two. Or three.
If I were you I'd be extremely PO'd that my one-year-old bike might be destined to become a single-speed for lack of a proprietary sacrificial part. That, or having to replace the whole rear transmission.

#2 i don't thing there is a "standard" for a RD hanger. All the ones i've seen are fairly specific to the model.

Not the manufactuer's fault, it was my fault it broke. I was being stupid. Lesson learned.
I'm also going to try and get extra spares for future incidents!

UPDATE: FAILURE! Broke while I was installing it 
But, I'm not giving up yet. Investigating drill & tap options next and even Aluminum Welding. I know a couple friends who might be able to help. I promised them beer in payment.

Would it be possible to recreate your own? It doesn't necessarily have to look exactly like the original; only the important bits need to be in the same places & line up.
Is there a machine shop local to you? They could fabricate something, certainly.
Alternatively... know anyone with a 3D printer?

But, I think we might have this licked with the machine screws holding it together after drill and tapped, it's looking good!

If you need more clearance you can grind the screws heads down. It's not like you plan on taking them out again.

Got it all back together, holding great and I'm probably putting more stress on it working on it than I will riding with it.
Went up and down the block a bit, seems fine. Got some more fine tuning to do tommorow.

I've enjoyed reading about your "Adventures in Derailleur Hanger Repair" and I hope it serves you well until you can get a replacement.
