Hubs on 2022 Specialized Roubaix Comp

Greetings! I picked up a brand new wheelset from a 2022 Roubaix Comp. Rims are DT Swiss R470db. Hubs are... yeah, who knows. The website says "Specialized full sealed bearing thru axle hub," but an in an online chat with Spesh I was told that they have no documentation for working on those hubs. No doubt they are rebranded, but from whom? Anyway, I have all the bits for the existing TA XD setup to QR Shimano (I know I have the correct parts because they came with the wheels). Can anyone steer me to the correct hub manufacturer or any other useful info? And in case anyone is wondering, there are no identifying graphics. Each flange on the rear has X U stamped into it, flanges on the front hub are stamped with U I D. Thanks!

The Axis hubs on my Tarmac seem to be very similar to many DT Swiss designs. It's very probable that Specialized has DT Swiss make Axis hubs exclusively for Specialized and no actual documentation for them is available to us.

Maybe chat up your favorite Specialized bike mechanic or just browse DT Swiss's assembly diagrams for something that looks close.

Making some progress through identifying the Shimano freehub, which is definitely a DT Swiss 11 speed ratchet hub. So, made for Spesh by DT. From pics,

it's obvious which of the adapter bits goes on the ds rear, but does anyone know which of the others goes where?

One could work from the drive side first and end up on the NDS to see which LH end cap fits your drop out width. Andy

The far right cap and the one on the freehub are DT Swiss end caps. I do not recognize the two caps on the left. The NDS cap is the one on the far right, the one with the silver.

Note that the QR caps on the NDS has two sizes, one for a 130mm and 135mm hub spacing. You probably have the 135mm, but something to consider when test fitting.
