It's me again.
The cabeling in the handlebars and stem has now worked, but there is a problem to lay the 4 cables in the area of the headset.
Currently I lay the cables from the handlebars through the compression ring into the frame to the brakes and the derailleurs and then try to install the fork. I try 2 cables left and 2 right from the fork tube to pass, but it does not work. Since the cables from Jagwire Pro Set are very rigid, I have enormous problems to install the fork and at the same time compression ring.
Does anyone have tips or a video what this explains well?
I have the exact same setup and routing is a nightmare though I gave up on Jagwire in the end. Despite that, the shifting is exceedingly smooth. It is Ultegra R6800 and when I compare it with my Fuji with external cabling and 105 R7000, Ultegra has faster, smoother shifts.
May be it its there but I can't find a video explaining the whole process. Here is what I did though:
1. Keep cables as long as you can. Finish ICR thru handle and stem and tighten the stem bolts..
2. Insert fork in the frame and with help of Velcro straps, tighten it to frame so it does no slide down.
3. Insert C ring. Insert dust cap without fail.
4. Take someone's help or if you can manage on your own - hold the handle/stem above fork steerer and start passing all the cables thru C ring into the frame and fork.
5. Front brake is easy. For rear portion, it is trial and error, fiddling and cursing for hours until all the cables have passed through respective outlets. There is no other way at least I don't know.
6. Front derailleur cable routing is tricky. You can route the cable above BB spindle or below. There is enough space in the frame to route it above the spindle but I found out going under the spindle is easier to bend the cable.
7. Once all cables have passed thru, assemble spacers and tighten stem to steerer.
8. If the bends in cable outer were reasonably fine, you should have no problem inserting cable inners.
9. Again, trial and error on shifting and braking action.
It is important to have proper cable ends inserted on shifter side. Without those you will have hard time inserting cable inners. Once you have successfully passed the inners, have one more set of cable ends handy for the other end.
