The audax tandem has Campag Ergolevers and Gore gear cables. They work fine now but they will need replacing eventually (hopefully not before the ACME Grand). I have a spare SS tandem gear cable for on-the-road replacement but I'm not entirely sure it is Campag-compatible. I would prefer to fit something as good as the Gore cables when these ones start to die anyway.
Are there nicer Campag-compatible tandem gear cables out there or do I need to go the coupled-cables route? If I couple a pair of solo bike cables, I can't use a fully lined cableset like the Gore cables.
