Please may I have some headset advice? I’ve got a steel frame with a straight 44mm head tube. And a 1 1/8th hylix carbon fork. Will this fit?

You need ZS44 both ends (i.e. ZS44/28.6 upper and ZS44/30 lower), or an adapter crown to fit a 1⅛" steerer in an EC44/40 lower if you want the extra stack of an external cup lower bearing, or the rare chimera EC44/30 lower assembly.

Thanks that’s really helpful.

If a 380mm axle to crown fork was specced with an external lower cup bearing, would the geo be the same with a 368mm fork and an internal lower bearing (assuming same rake)
