Great input and ideas!
I don't mind internal frame cable routing, but integrated cockpits are a new and daunting development for me.
I appreciate the looks and watt-saving potential. But, on balance I think I prefer the flexibility and serviceability of a regular cockpit. However, if the frame ticks all the other boxes, I'll settle for a semi-integrated solution.
Thanks very much!

Folks,

All the Chinese frames I’m interested in – like the ICAN FL1 – appear to feature fully integrated cockpits.
I’m wondering if it is possible to set them up with externally routed hoses/cables and a separate bar and stem?

If it is possible, how much work, hassle and/or extra parts is needed to achieve it?
Is it as simple as a clever bottom spacer that lets you run the hoses and cables into the frame through the head tube?
I’ve never worked on a fully integrated bike, so it’s a mystery to me.

I’m happy with internal routing through the frame. But I’d prefer a bit more flexibility in the cockpit to accommodate travel or swapping bars and stems.

Any advice and guidance would be most welcome.

Cheers
