Hey guy, had a crash on Thursday and my left side Dura Ace 9170 shifter is not shifting. Brake works fine. My mechanic opened up the shifter and noticed cable was severed. He told me that it was not repairable. Just getting second opinion here.
The cable is probably repairable, I'd try if it was mine but I wouldn't offer to do it for a customer because it would be time consuming and not guaranteed, and isn't the lever broken anyway?
