I recently finished to assemble the new groupset and noticed that the left shifter does a gliding sound accompanied by a very slight resistance at the beginning of the travel. The resistance drops very fast at the same time in which the sound can be heard.
I have tried to re-blead both brakes to see if it was something that i had done wrong but to no avail the sound is still there, and possibly even slightly louder, but there i don't know if it is just in my head.
I don't know and kinda hope it can have any impact on breaking performance and reliability, but just checking if anyone had a similar experience and if they solved it.

The  clicking noise in the video is way louder than in reality, when i move to film the other shifter i was not even able to hear anything while filming. At the same time the gliding sound seems to be quite muffled compared.
