I have a sort of 'click' that occurs, it sounds like a flexing 'click' based on when / how it happens, it isn't something you can feel at all. It's been there since about the second week of usage, and is possibly slightly louder now than it was, but I wear headphones so don't tend to notice it as you can't feel it.
I've not managed to recreate it by just pushing on the wheel or anything, it's a specific sort of combo of rotation with resistance and so on that seems to trigger it. Doesn't bother me really due to the headphones, although obviously it would be more reassuring if it didn't make the noise...!
Otherwise it feels absolutely fine. Have had it since the new year, probably done a few thousand miles.
