I've been looking around for 118 link 12 speed chains and can't seem to find any sellers of them other than aliexpress or chinese sellers. My chain breaker can't seem to remove a link from my 12 speed chain. How have others managed here? I'm guessing bike shops may be able to request these from Shimano.118 from memory, though not 100% as it's been a while since I counted it.
I do believe your 118 link is correct.
