Hello, had a problem with my 8050 lever, it just stoped working. I disassembled it and I see the buttons and connector part is one that can be easly changed but cannot find it. These are the numbers in the part:
Any chance someone knows where to get it?
It started when I accidentally forced my rear wheelset in place where the Rear derailleur pulley and chain where also forced in place, because I forgot to put the shifter to the smallest cog. After that my Di2 RD won't shift anymore smaller than the 5th cog, it can shift up to the bigger cogs...
