If its the norm, which is unusual, I have seen a youtuber named oz cycle who has a youtube video dealing with headset space and how to protect it from water using a rubber gasket or a seating washer titled Thread cables thru frame - How to {you can start clip at 2 minutes in)

When i see all the flat sections on the 017-d i doubt this frame is having good aero performance.
Down tube, seat tube and seat post are totally flat right in the airflow...


About the reach/stack you must take account that frames need special spacer to ensure cable routing, thus you can add at least 1,5cm to 2 cm for real stack and 1cm less for reach.

About workswell, they are not selling a lot for single customers.

Your all aero experts now? 

Unless the bike is dedicated aero bike, square-ish down tube is fine. Cannondale SuperSix Evo 4 has square downtube as well, yet with Cannondale's own 50mm wheels and 2 piece handlebar it is on par or better with quite a few dedicated aero bikes.

That comes with buying a frame direct from manufacturer. If you get your frame on time, they either have it in stock or you got lucky. If it is delayed when it's being manufactured, that's normal.

Great looking Bike!

How do you like it thus far? I see, that you got the C67DB (?) wheelset. The pattern looks very subtle, I like it. The hicups were nothing major I suppose?
