I've noticed on a lot of the '21 models, the headsets are listed as:

FSA Orbit NO.57B | 36°x45° Bearings | 30.2mm x 41mm x 7.1mm Upper | 40mm x 51.8mm x 7.5mm Lower

For example, the Blizzard frame has this headset, but also lists the frame as having a "Zero Stack Tapered Headtube"

Is this just a standard ZS 44 / ZS 56 interface? I have a few Cane Creek's laying around the garage and this Orbit No.57B is pretty crispy out of the box.

Thanks for your help!

Yes, no change in standard, just added some more detail in case anyone needs to replace their bearings.
