Ok let’s see if I can say this differently. Forget about shifting because it does not happen when I shift.
It only happens while I am pedaling at a constant rate on level ground and not hesitating. The wheel speed seems to change momentary between each rotation as if I’m missing a couple of teeth. It only happens when my right foot is going down and my left is coming up. I don’t know maybe its just me.
I paid a guy to adjust the detailers so I don’t think that’s it although I guess I could take the bike back to him to check it out
