What do you mean by "odd completely flush lower headset"? Pick one: https://www.parktool.com/blog/repair...dset-standards
Good reference site. Anyone have comments on the advantages or
disadvantage of the various "standards"?
Good question. Think of it as the new golden era of headsets -- after the last golden era of headsets (English/JIS/Swiss/French/Italian -- and whatever Andrew identifies). The good news is that we're again reaching a stasis -- integrated, although there are several flavors of integrated. The other good news is that the bearings last a very long time. I'm using the HS from my totaled Supersix in my CAADX. Installing the headset took five minutes, or six minutes (I had to install a crown bearing seat). The other bikes have molded bearing seats.

O.T., but still bicycle related, I had a draggy front disc on my Synapse, so I decided to take off the caliper and clean the pistons, and when I took off the caliper (flat mount), a bunch of water came dripping out of the caliper mount holes, so I dropped the fork and poured out the water. I probably reduced bike weight by 40 grams. Having a integrated headset made it super easy. I do wonder, however, how the water got in there.

Tell me Jay - if headsets are so standardized why does Cane Creek make 14 different sized?

Standard design, different dimensions. It's pretty simple, either match existing bearings or measure the ID/OD or go to one of those pages that tells you what the bike takes. I linked that Tange headset (which was the "Campy" standard), but the Douglas probably uses the Cane Creek standard, which is a IS41/28.6 IS41/30. https://tinyurl.com/33pakzck Just measuring the ID of the upper internal cup will tell you.

A lot of the different combinations have different upper bearing covers that vary in height and width to match personal desire or frame design. They're more or less cosmetic. My son wanted to slam the stem on his Emonda, so I switched the upper cover for him. Not this one, but slamming the stem is a thing. https://www.certifiedslammed.com/ Knock yourself out: https://tinyurl.com/3csdcj7a

You have hundreds of pounds of tools. This should be easy for you.
