So I started riding a little earlier in the day after work & haven't needed my headlight (and mount) as much so I just removed it. I assumed that it was the flashlight mount that was creaking but I think it's the whole handlebar/headset/brifter assembly.
It's a SuperSix EVO 3 so it's got carbon steerer & I'm pretty sure bars are alloy and then Ultegra 6800 brifters.
I asked a guru who I do local rides with and he strided my bike gripped & wrestled my handlebars & said my headset's fine. So I asked if there's anything I could lube & he said, front brake mount hinge & that's it. (I figure it's something that wouldn't bother him).
It's not a big deal but any ideas??? TIA
