Ok, PF30 bb shell, so got a Praxisworks press fit BB which uses a sleeve that presses flush right up against the shell. It has cut outs in it that align with the stays for internal routing.

But how the hell do you actually route the Di2 cables? Do you need to fit the NDS side and then route? Not sure that the junction box will fit through the cut outs.

I realise it’s a bit of a niche problem, but any wisdom gratefully received 🙂
