Just got a new Ribble R872 and it came fitted with RS31's. The rear wheel has a very small gap in the rim which I can hear grating when I brake. The front wheel has no such gap, and neither do any of the other pairs of wheels I own.
I've attached a photo of what I mean. I guess there maybe two problems here: the brake pads will get shredded quickly as the gap is very rough to the touch and b) the wheel is actually faulty and will collapse at some point.
So my question is: is it normal to have a gap in a rim like this?
