re the pic attached. Just bought a Bianchi Infinito. The headset has an open hole. I would normally expect a blanking cover or screw as I've had with past FSA headsets. Seems odd to me that it's just an open hole that can fill with grit, water etc. Can't find a clear picture on the net to confirm if this is how it should be. Anyone have one? Is there a bit missing or am I being silly?
