Bent derailer hanger on Scott CR1

[Jules]

Today I bent the derailer hanger on my Scott CR1. The hanger is not replaceable. The bend is pretty serious .

 

 

 

Consulted some bike shops, who in turn consulted ProBike, and I was informed that to fix it, the lug would have to be removed and re-inserted in the carbon.

 

 

 

Considering that this would mean throwing the lug away, I instructed the LBS to try bend it back before removing it.

 

 

 

Would like to hear the technical opinion of hubbers please. I was told heating the hanger prior to bending would not work because it would damage the carbon.

jules we got our customer, who has the same frame as yours, a new one from scott in australia. its a design flaw they should've never put in the bike, fight with the agent, they must replace it!

BMC in cape town fixed mine last year for R350. They have a technician that does exceptional alu welding. They simply welded a new one on. You wont even notice the difference.

What will Probike charge to replace the insert?

If it costs a lot, have an expert like JB bens it back. If I am not mistaken, the metal will take 1 attempt at bending streight. After that, it breaks off more easily - guess due to work hardening?

How did you bend it?

I crashed. Think i smashed the derailer into the tar, which bent the hanger. Probike doesn't do the repair job themselves. They suggested I contact Bill Erwin, the carbon expert. Welding sounds like an interesting option...

If they are going to replace it, see if they can machine the replacement to take a Raleigh (Kenesis) or Giant replaceable hanger.
