Re droppers, my research leads me to understand the dropper usually requires a cable between the dropper's base and the handlebar control.
Since my bike is carbon, I'm reluctant to go drilling holes for the cable and I can't see any cable exit provision was made by the designers either.
Nope - externally routed droppers have a cable that's routed from the outside of the dropper to the handlbar along the frame - like your brake cables.
Mine has an externally routed dropper, as i don't have internal cable routing.
I'll see if I can find a pic that shows it adequately.
