cable routing is all good. I did in fact sort it by the new cables previous to riding last night; re-lubed the cables they move freely when you disconnect it same with pushing the mech up and down. tightened up the cable a little bit as it was slow to shift up as i got a little be of cable stretch from riding with a new cable; and it’s back to square 1 checked the cable is bolted up in its guide properly too!
