Campagnolo cabling: can I use other non-Campagnolo brands?

You don't have to buy Campy brand cables, but you do have to buy Campy-compatible cables, because they use a head that's a little bit smaller for both shift and brake cables. If you ignore this, it ...

Why do hydraulic brake/shifter lines cross in front of the handlebars?
