I ordered some Onirii BR-05, some jagwire compressionless housing, slick brake cables, and some cheap bar end levers. $66 US after tax. Much cheaper than anything fully hydraulic. The calipers are mech hydraulic and I read reviews that they are nearly as good as Juin Tech F1s which should be plenty of breaking power for flat course racing.

If i understand that correctly, for TT we can run AXS with just blips and RD/FD.
Im not familiar with sram, but the Apex AXS XPLR described to work with Shimano HG cassettes.
Does that mean I can just update my setup above with just Apex XPLR RD and Blips swap (and put shimano 12sp 11-30 cassette)?

As far as the XPLR RD goes,  SRAM says the XPLR is only compatible with 10-36, 11-44, 10-44 cassettes. You may have issues going down to the 11-30.

May be better off getting a standard Rival AXS rear derailleur which is specced for 30-36T cassettes. If you are in the US, I often see them for significantly cheaper than XPLR RDs.

I use wireless blips on my road bike with aero bars, it's awesome. I just ordered a TT Frame off Ali and plan to move everything over to it. Going to get some ~$150/pair Juin Tech F1 hydro-mech brakes with some $10 levers and use two sets of blips, one pair on the extensions and one on pair on the base bar. Paying $400-500 for SRAM/TRP/RideRever hydraulic bar end brakes.... I can get a set of AXS Force shifters with calipers for that. No thanks.

The force shifters on the road bike are going to a gravel bike. Road frame is going to be sold or live on the trainer. Haven't decided.

EDIT - Apparently I can get RideRevers for $269 a set, that may make them better than the Juin Techs in the long run. Hmm

I see that it's up on the website, how do you get the fork without bolt holes? Is it also possible to get the frame with fewer holes?

When I messaged them via email, they said they could do the fork without bolt holes. They also said they will eventually have semi-internal available. Probably if through AE would need to put a note with your order.

I'm disappointed they went with the upper side of Canyon's crazy sizing. I need a 2XS.

Probably going to have to go with the CFR707 to get UDH + BSA/T47 + standard seat post + good tire clearance + semi-internal.
