headset

Would anyone happen to know what the specs are for a Chris Boardman Team Carbon lower bearing on the headset?

Is it a 1.5" 45x45 or a 1.5" 36x45?

Hill climb bikes.

Bloody hell.

Especially the guy at the end who removed his whole headset pretty much.

Hi

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?

This is might be a bit of a stupid question but I've just bought a Campag threaded headset for my GF's frame. I've just taken it out of the box and checked all of the pieces and there don't seem to be any ball races.

Do these headsets simply not need them?
Am I supposed to buy them separately?
Or have I got a duff headset and I should return it?

Thanks

Mark
