I agree on the exposed cables. Are those prices and specs for mech setups? I didn't look closer. On any modern aero bike I will personally NEVER own another without Di2. The mess of running mech cables in some of these bikes is rough. Sure, rear brake. But that's usually the easiest cable run.

And if those bikes are Di2 (or SRAM equiv), there's zero reason for all the exposed routing since the wires are smaller/easier to hide places than mech cables are that require a big enough bend radius to still work correctly.
