Having trouble figuring out which lower headset I need from Cane Creek for a 1 1/4" tapered fork and a 44mm head tube. Ideally I want a 110 series ZS44 and CC only lists one, the ZS44/30. Will that fit?

If not, then I have to get an EC44. But which one; the EC44/33 or the EC44/40?

Here's the link to the page. I emailed them last week but haven't heard back yet.

Thanks in advance.
