Okay, so some interesting new discoveries:
There's this
fully integrated SLC 2.0 using the Winspace Zero cockpit and
this other example, both with the external brake holes still in place. I'm unsure if a hole had to be punched in the fork steerer or if the stock fork comes with provisions for external and internal routing to begin with.
Looking back at that
fully integrated Adris Soar, the cockpit looked more like the
Speeder SC-RH02 than the
Winspace Zero. Where it gets interesting is that there may be more players in the Speeder/Winspace/Gotobike circle than I originally thought. The SC-RH02 cockpit looks the same as the
Adapt AHD-01 and
Edge Design HB-20 while the SC-R49D frame looks the same as the
Adapt FM49-DB and
Edge Design Aeolus.
Adapt also has frames that I couldn't find anywhere else like the
AT-B01. They seem like a legit OEM supplier too as the
Olympia Leader seems to be a rebrand of the
FM08-DB frame.
And since Adapt states that the AHD-01 accepts fully integrated mechanical groupsets, the Speeder SC-R49D & SC-RH02 combo should be compatible too. All we need now is for Speeder to update the SC-R48D to work with that cockpit and we should be good.
