Routing FD cable

[GeorgeET]

Ye that bottom hole is way to small to put a splice through. It either has a guide tube or as X said you need to work it through the BB.

I got the rear brake cable going through the top frame tube, no idea how I would replace that if it broke. PITA.

10-4 on bad engineering vs repair needs.You should try working on a BMW motorcycle sometime. :-)))

Good clear photos BTW.
