Headset Cone Spacer thing - Help.

I've got a Specialized Allez as a 2nd bike and I want to make the geometry of the bars the same as my Specialised Tarmac which has been professionally fitted.

To do this I've worked out that I need to remove a load of spacers from the steerer (going for the standard 40mm to 13mm)

However the conical spacer that comes on the headset is 22mm including a small cover below it.

My question is can I run without the conical spacer and just run my spacers on top of this cover?

This is what it looks like when I remove the cone spacer:

    If that's under the conical spacer I reckon you can. Is there anything to the conical spacer other than just being a tall spacer?

    The cone spacer does have a O ring inside it so I assume it's another seal against water ingress

    If the headset minus conical spacer includes some kind of seal as well I reckon it would be OK. My headsets only have one o ring seal.

    It's fine to just run with the lower cover
    FFS! Harden up and grow a pair :D

    Ok, on my bike with an FSA headset I only have a flattish thing like in your first picture that has an o ring in it. As above does yours have an o ring as well as the one in the cone? If so it'll be fine, if not you may be able to find a flatter spacer with o ring. I was given one by the workshop of my LBS when I asked about getting one. They just had a few spares kicking about from previous jobs done. Might be worth a go. Although to be honest I don't know how much water would get in through there. You could just stick an o ring under that cap.

    I'll have a look tonight, I'm pretty sure it's got a seal on it

    If it hasn't the replacement bearings are only £17 so I might just run with it anyway and make sure the bearings are greased up well (I'm pretty sure the bearings are sealed anyway)

    you could even just pit a smidge of silicon sealant under that flat cap - will do the same as an o ring but seat better
