A quick check before I cut...
I am used to the old school way of running all cables so they loop around the head tube but that seems to be out of the window these days.
Rear shifter: outer (right) most cable stops, drop down towards bottom headset cup and loop up into right shifter.
Rear dérailleur: nice and obvious.
Front shifter (yeah I know, other bikes are 1x11, this is staying 3x10): inner cable stops, loop around right side of head tube to front shifter
Front dérailleur: cable stop is canted over to the left as you would expect so run the cable round the left hand side of the seat tube? The reason I am unsure is the cable stop is quite a way over to the right of the top tube.
Rear brake - run up the left side and head round to the left brake instead of cutting back over the right and looping around the head tube? Reverb cable tied to it and doing likewise to the left side of the bars. Might leave this looping round the head tube as it uses more hose and I can't be bothered shortening it.
Having a combination of cables looping and some on the same side is setting off my OCD 😡
answering my own question looks like the FD cable is supposed to go round the right side of the seat tube. Bit of a tortuous route 😕
