Nuke Proof Headset Compatibility

I´ve been looking at this headset:

From what I read it seems like it will fit a 44mm Head Tube (that takes a standard 1,1/8 Steerer) but will let you run a 1.5 Fork since the bearings are external, not inside the headtube. Am I wrong?

This would save me selling my 1.5 Lyric just to buy a 1,1/8 one to fit my new frame.
I emailed Nuke Proof so if they reply I´ll post it here.

yes and no.

the problem is the insert depth.

there is no requirement in the standard for them to be-able to manage 20mm insert depth.

the standard now says 15mm min but most take less. 10mm being normal.

but you may be lucky.

I was looking at that too and the headtube in my frame is carbon and as far as I can make out its the same width and texture all the way down. I´d assume this really only aplies to aluminium headtubes since they´d have to be reamed during production.
Nuke Proof also make a 14.8mm insert version.

I also came across another forum where a guy with the same NukeProof headset, cut the inserts to fit his headtube, an Orange Five. It worked fine.

as long as the cut left a smooth chamfered edge it is fine.
