Last night my 7970 stopped shifting. The junction box seemed to be fine, but now if I move the FD TT shifter to the RD, it works. But that's it, very weird and hoping I can get some parts (cheap-ish) before my next race on Oct 17th.

I've found a couple in stock at stores, but would rather pay someone here for parts they have laying around.

Looking for the junction box, bar end shifters and even brake shifters depending on the price.

Part Numbers:

SM-EW79A-E or SM-EW79A-I
SW-7971
ST-7971
