UPDATE: is this shifter hosed?
I got the thing all installed and cabled up but when I tried to shift it, it wouldn’t shift up to move the front derailleur over the big chainring. It seemed to hit a wall - and the down shifts were funky too.
After trying it again today, I noticed that something was sticking out of the same hole as in my first picture and the cable guide was catching on it, and also the cable guide was still trying to come out of the hole instead of rolling down forward past it.
Any idea what this piece is? Honestly it looks like a twist tie you close a bag with at the grocery. But it also runs back down inside the Brifter - no idea what it’s purpose is. It looks like it’s been busted. Thoughts? Is this thing done for?
